Design your eflow — color, logo, and font

Everything that makes a conversation look like yours lives in one place: Settings → Branding. It is an account-wide setting, not a per-eflow one, so every eflow you send is consistent without configuring each one.

There are three controls, and a fourth that only affects hosted links.

Brand color

Seven presets and a hex field. Set one color and the whole conversation takes it: the launcher, your own message bubbles, buttons, and the progress indicator.

Under the field is a contrast reading against the chat background, with the ratio spelled out. If your color clears 4.5:1, respondents see it exactly as you picked it. If it does not, links and labels in that color would be unreadable, so the widget deepens it in the chat and tells you which shade it used instead. Nothing is rejected — you are told what will happen. Pick a darker shade if you want an exact match.

Your logo

Upload a PNG, JPEG, or WebP up to 512KB. It appears in the widget header and at the top of the hosted eflow page.

Where it lands depends on the shape of the file, and you do not choose — Acquainto measures it. A file twice as wide as it is tall, or wider, is treated as the version with your company name written in it, so it runs across the full width of the header on a strip at a height we set. It is scaled to fit, never cropped, however wide the conversation is. Because that file already names you, your organization name is not printed underneath it as well. The strip is white unless you change it — see below.

Anything squarer than that is treated as a symbol and sits in the small circle beside your organization name, which stays as text. A symbol carries no words, so the text line is the only thing naming you and it has to stay.

If you want the wide treatment and are not getting it, the file is not wide enough — a logo with generous empty margins baked into it measures squarer than it looks. Crop the margins and upload it again.

The strip only ever appears in the header. The small logo beside each question in the conversation has no room for it, so a wide file shows your organization’s first letter there instead — the same fallback a tenant with no logo at all gets. It is not a smaller, cropped copy of your logo; nothing about the file itself is shown in that spot.

With no logo set, respondents see the first letter of your organization name on your brand color. If your name has no letter to take, they see nothing rather than a placeholder.

“Use my logo’s color”

Once a logo is uploaded, Acquainto reads a color out of it and offers it to you just below the palette. It is only ever an offer. Hover or tab to it and the live preview shows the candidate on the real header; the color is not saved until you click. Changing your logo will never silently repaint conversations that are already running.

Sometimes the offer is a darker shade than the one in your logo. That happens when the original would leave white label text unreadable; the panel says so, and names both shades.

The color behind a wide logo

A wide logo sits on its own strip, and Logo row background sets the color of that strip. It is white unless you change it, and the field only appears once you have uploaded a file wide enough to use the strip — a square logo sits in the circle, where there is no strip to color.

Four swatches, plus a hex field for anything else: white, a pale tint of your brand color, your brand color itself, and near-black. Under them is the strip drawn as respondents will really see it, with your own file on it, at both sizes it renders at.

A color that would hide your logo is not saved. This matters more than it sounds. If your logo is drawn in your brand color and you set the strip to the same brand color — the obvious thing to reach for, and it is the field right above — your logo vanishes completely. Not faint: gone, on a screen where nothing would tell you. So each swatch is marked before you click it, and choosing one that fails shows you the strip, tells you the contrast it measured, and leaves your saved color where it was. It also offers the nearest shade of the color you asked for that your logo does survive.

If your brand book has a knockout version of your logo — the all-white one drawn for colored backgrounds — that is the file to upload if you want the strip in your brand color. It is the pairing this control exists to make possible.

Two other things it will tell you:

• Your file brings its own background. JPEGs cannot be transparent, and neither can some WebPs. On any color but white, such a file draws its own white rectangle around your logo. That is a warning rather than a refusal — the preview shows exactly what you get, and it is yours to accept. A PNG with a transparent background removes it.
• We cannot check this file. Photographs and gradients have no flat ink to measure. Nothing is refused; the preview is the check, so look at it.

Your icon

A second, optional upload: PNG, JPEG, or WebP, up to 512KB, for the small round icon that sits next to your organization name — in the widget header, beside each question in the conversation, on the start screen, in the browser tab, and in link previews.

With no icon uploaded, that circle falls back to your logo (unless it’s a wide file — see above) and then to your organization’s first letter, exactly as it does today. Upload an icon and it takes over that circle everywhere the circle is drawn, immediately.

A wide logo is the one place the circle is not drawn at all. The strip across the top of the header already names you, and an icon beside the line underneath it started that line well to the right of the logo above — two halves of one identity block, visibly out of step. So with a wide logo the header is the strip on its own. Your icon still appears beside each question, on the start screen, in the browser tab and in link previews.

Because the circle is drawn on your brand color, an icon in that same color can be hard to make out. If Acquainto measures your icon as too close to your brand color to read clearly, it says so under the upload — the icon is still saved and shown; the note is only there so you know to reconsider it, or the color behind it.

Font

Twelve faces, on every plan. Seven sans, three serif, two geometric, each with a line on why you would choose it. They are ordinary body faces rather than display faces, on purpose — a respondent reads this text for several minutes.

Every one of them covers the accented characters our published conversation languages need, so a Polish or Turkish respondent’s own name renders in the face you chose rather than dropping to a fallback.

Pick nothing and conversations render in the default interface face.

The page behind the conversation

By default the page around the conversation card is a neutral gray, on every account. If you would rather it carried your color, turn on Brand color behind the chat card, just under the color itself.

It applies to the hosted links you send. It does not change a conversation embedded in your own site, where the page is already yours.

It is off until you turn it on, and it needs a brand color to work from, so the switch stays disabled until you have set one. It is a wash of your color rather than the color itself — we work out how light or dark it should land so the card stays easy to pick out, and so the same setting works for someone reading in dark mode.

The Acquainto line at the bottom

By default Acquainto’s own name appears once, in small type, at the bottom of the conversation and of the hosted page.

Some plans include hiding it. The checkbox is in the same Brand panel; if your plan does not include it, the checkbox is disabled and says so rather than letting you tick something that would not take effect.

Ticking it also changes the small icon a browser shows in the tab, on the hosted links you send: your own logo instead of Acquainto’s mark. Left unticked, those pages carry ours. It is the same one switch — you do not set the tab icon separately, and there is nothing to upload for it beyond the logo you have already set in this panel.

Two things it does not touch. A conversation embedded in your own site takes your site’s tab icon, because the page is yours. And the preview card that appears when someone pastes one of your links into Slack or email keeps your organization’s name and your logo on it either way — only the small tab icon changes.

One thing the widget always tells a respondent, on any plan or any surface: AI assistant. It sits in the header now, next to your eflow’s name and its time estimate — moved there from the footer, so it is one of the first things a respondent sees rather than something in the footer they may not scroll to.

Header subtitle in Settings → Branding replaces that line with wording of your own — We usually reply within a day, say, instead of the eflow’s name and its length. The disclosure stays on the end of whatever you write. The line is yours to word; it is not yours to remove, and respondents are always told they are talking to an AI.

The Privacy link is a separate thing, and lives in the footer of every conversation. It is unconditional: set a privacy notice URL in Settings and the link goes to yours, leave it unset and it goes to Acquainto’s own notice. It cannot be switched off, and it is there on your own site as much as on the links you send.

It used to be conditional — an embed on your own site with no URL set had no privacy link at all — which is why there was also a separate line above the first question saying where the answers went. That line is gone; the footer link now covers every case it covered. Setting your URL still swaps Acquainto’s notice for yours everywhere at once.
