What Is the Difference Between Brand Colors and UI Colors? How to Use Them in Web Development
Should the color in a company’s logo also appear on every website button and text label? Brand colors help people recognize a service and its visual identity, while UI colors help people read information and use the interface. UI stands for user interface, including the buttons, forms, and other parts of a screen people interact with. The same color can serve both purposes, but separating the purposes first usually makes design choices clearer.
Brand colors express identity; UI colors support tasks
Brand colors connect the logo, product presentation, and decorative details with the service’s identity. UI colors, by contrast, need to cover several functional roles: text, surfaces, primary actions, form fields, and status messages. Think of UI colors as a set of colors assigned to different jobs, not a single alternative to the brand’s main hue.
When a brand color is dark enough to give text or a button label sufficient contrast, it can also serve as a primary action color. But a bright brand color may provide too little contrast with small white text. It is not necessary to force the brand color into every interactive component. Begin by deciding which places communicate brand identity and which need to be easy to read, select, or operate.
Example: separating brand accents and actions on a food subscription page
Imagine a food subscription website with bright orange branding. A HEX code is a hexadecimal notation used to specify a web color. In this example, orange is reserved for the logo area and small accents, a dark blue is used for the subscription action, dark gray-blue handles the information, and a separate green pair indicates a completed order.
| Color role | Color and HEX code | Use on the page |
|---|---|---|
| Brand color | #F2A43E | Around the logo and as a small heading accent |
| Page background | #F5F7FA | Outside the subscription-plan cards |
| Card background | #FFFFFF | Delivery options, quantities, and pricing |
| Main text | #243447 | Product names, amounts, and terms |
| Supporting text | #536476 | Delivery-date notes |
| Primary action background | #175F85 | “Subscribe to this plan” button |
| Primary action text | #FFFFFF | Text on the dark blue button |
| Essential borders | #75889B | Outlines of cards and input fields |
| Success notification background | #EAF7EF | Message displayed after an order succeeds |
| Success notification text | #176446 | “✓ Your order has been placed” |
Bright orange #F2A43E has a contrast ratio of approximately 2.07:1 against white #FFFFFF. Therefore, do not use it unchanged for ordinary small orange text on a white background or as the background of a button with white text. Dark text #243447 on an orange #F2A43E surface, by contrast, gives approximately 6.13:1. For this page, keep orange around the logo and as a short decorative accent rather than relying on it for the main action.
For the “Subscribe to this plan” button, use dark blue #175F85 with white #FFFFFF text. The contrast ratio of the label and button is approximately 6.97:1. The button also differs from the pale page background #F5F7FA by approximately 6.50:1. Place the secondary “View delivery terms” action as an underlined dark-blue #175F85 link on a white #FFFFFF card, so the primary and secondary actions do not look equally prominent.
Main text #243447 on a white card #FFFFFF has a contrast ratio of approximately 12.67:1; supporting text #536476 on the same white background reaches approximately 6.08:1. White cards #FFFFFF and the pale page background #F5F7FA differ by only about 1.07:1. Wherever a boundary is essential, use an outline in #75889B: its contrast is approximately 3.65:1 against white and 3.40:1 against the pale page background.
Once an order has actually been completed, display “✓ Your order has been placed” in deep green #176446 on pale green #EAF7EF. The text/background pair measures approximately 6.46:1. Do not reuse the brand’s orange as an arbitrary success state; spell out the result as well as showing a status color.
Keep the identity consistent, but test UI colors in context
Using different brand and action colors does not necessarily make a website feel disconnected. Repeat the brand color consistently in identity-related locations, then use the same functional colors for the same kinds of text, controls, and messages. When a brand color changes, review the affected components rather than automatically changing every UI color along with it.
WCAG (Web Content Accessibility Guidelines) 2.2 Level AA requires at least 4.5:1 contrast for normal text and 3:1 for qualifying large text. Essential visual information in UI controls or graphics must generally reach 3:1 against adjacent colors. Text within logos and brand names is exempt from the text contrast criterion, but ordinary explanatory text using that same color is not exempt. The ratios in this article are calculated for opaque solid-color pairs; they do not demonstrate compliance for an entire page.
HueRoll lets you inspect HEX codes, lighter and darker color suggestions, and contrast against white or black. It cannot directly compare any two arbitrary custom colors or automatically certify AA or AAA conformance. Verify the actual text, surface, button, and border combinations separately before putting the palette into use.
