You've just chosen your brand colors: the right ones, the ones that represent you.
Then you apply them to an element on your site, and something stops working. The text is hard to read against the background you picked, or the success and error states look identical to someone with a form of color blindness.
This happens because a palette designed for a logo follows different rules than one designed for an interface.
An accessible brand palette preserves visual identity and ensures that text, states, and components stay readable for everyone who uses them, including people with visual disabilities.
In this guide, we'll look at how to build one, step by step, without giving up your brand's character.
How to build an accessible color palette in four steps
Building an accessible palette means organizing the colors you already have around specific roles, testing them, and covering scenarios that a logo alone never has to face. The process breaks down into four steps, from auditing your existing palette to checking it for color blindness.
Step 1: Audit your existing palette
Before changing any color, you need to know what isn't working today. Take your official brand colors, one by one, and test them in different combinations: text on background, button on background, icon on button. Standard logo combinations, static and isolated from context, aren't subject to a minimum color contrast requirement. The problem arises when those same colors become text or interface elements.
The Web Content Accessibility Guidelines (WCAG) set precise thresholds for AA conformance: normal text requires a contrast ratio of at least 4.5:1, large text at least 3:1, and essential graphical elements (button borders, status icons) at least 3:1, under criterion 1.4.11.
The audit itself means measuring every pair of brand colors against these thresholds and marking which ones pass and which don't.
Step 2: Build accessible variants without overhauling your brand
When a color fails the test, replacing it is rarely the solution. More often, all you need is to build a family of variants around it with different roles: a darker shade for text, the original hue for decorative accents, a lighter shade for backgrounds.
A brand green that's too light to work as text on white can stay untouched as a background color, with dark text on top of it. Or you can darken only the variant meant for text, keeping the original green everywhere contrast isn't at stake: logos, illustrations, decorative elements.
Step 3: Cover interactive states, not just the resting color
A palette designed only for an element's "normal" state leaves exactly the moments when users need clarity most uncovered: when they hover over a button, when they navigate by keyboard, when a field is disabled or flags an error.
Each state needs its own contrast check, not a visual approximation:
Hover and focus. The keyboard focus ring needs a contrast of at least 3:1 against the adjacent background.
Disabled. A minimum contrast isn't required here, but you do need a visible style change (a dashed border, a lock icon), not just reduced opacity.
Error and success. Color alone can't be the only signal: an error field also needs an icon or a text label, not just a red border.
Step 4: Check the palette for color blindness too
A correct numerical contrast doesn't guarantee that two colors stay distinguishable for someone with a form of color blindness. Red and green, the most commonly used pair for signaling error and success, are among the hardest combinations to distinguish for people with red-green color vision deficiency, the most common form.
To check this, simulate the palette with a color blindness simulation tool (protanopia, deuteranopia, tritanopia) and see whether the semantic pairs stay legible.
If two colors get confused, the most effective fix is almost always the one already used in step 3: pair the color with an icon, a text label, or a pattern, so the information never depends on hue alone.
Accessible color palette: create and test color combos
Checking a palette pair by pair, by hand, takes time once you're dealing with more than two or three colors. A color contrast matrix solves this by showing every contrast ratio across all possible combinations in your palette in a single grid, with the conformance level (AAA, AA, AA large text, not compliant) flagged for each cell.
You can enter your brand colors and immediately see which pairs are already ready for normal text, which only work for headings and large text, and which need revisiting per step 2. For a broader audit that also covers interactive states, components, and EAA compliance, the Accessiway team can help you define your design system's entire color system.
Why color contrast isn't just a conformance issue
About 2.2 billion people worldwide live with some form of visual disability, according to the World Health Organization. On top of that, a significant share of the male population has a form of color blindness: roughly one man in twelve, compared with a much lower percentage among women.
An accessible color palette translates into a better user experience: fewer form-filling errors, fewer drop-offs on pages with hard-to-read text, fewer support requests for problems that higher contrast would have prevented from the start.
An accessible palette also helps people reading a screen in direct sunlight or on a low-quality monitor, not only those with a diagnosed visual disability.
Before you go: the points to apply right away
Building an accessible brand palette takes three changes in habit, not a color revolution:
Start from roles, not colors. Text, background, success state, error state: each role has a different contrast threshold to meet.
Document the variants as part of the design system, not as temporary exceptions, so the work you do today stays valid when the team changes or the site gets updated.
Always add a check for color blindness: two colors can pass the WCAG threshold and still be indistinguishable for part of your audience.
You can start by testing your current palette with the color contrast matrix above, to see which pairs to prioritize first.
Frequently asked questions about creating an accessible color palette
What are the minimum contrast ratios required by WCAG?
For level AA, normal text requires a ratio of at least 4.5:1, and large text at least 3:1. Level AAA raises the thresholds to 7:1 and 4.5:1 respectively. Essential graphical elements, such as button borders and status icons, require at least 3:1.
Can an accessible palette stay vibrant and original?
Yes. Staying accessible doesn't mean limiting yourself to black text on a white background. Many brands keep colorful, recognizable palettes by organizing colors by role: one shade for the background, a darker or lighter variant for text, so the visual character stays intact.
How do you check a palette for color blindness?
You simulate the palette with a tool that models different forms of color blindness (protanopia, deuteranopia, tritanopia) and check whether the color pairs used to convey meaning, like success and error, stay distinguishable. If they aren't, you pair the color with an icon or a text label.
Do you need to redo your whole brand kit to make it accessible?
No. In most cases, it's enough to build accessible variants of your existing colors, assigning different roles (background, text, accent) to different shades, instead of replacing your brand colors.
What's the difference between contrast and color accessibility in general?
Contrast is the difference in luminance between two colors, measurable as a numerical ratio. Color accessibility is broader: it includes contrast, but also how color communicates meaning and how legible it is for people with color vision impairments.
