What to Check Before Adding a New Accent Color
When a website needs to draw more attention to a recommended plan or new feature, adding another accent color may seem like the obvious solution. An accent color is used in a limited area to draw attention away from the surrounding palette. But more colors do not automatically make information clearer. Before adding one, check what the existing colors already communicate and give the new color a specific purpose.
Check whether existing colors and layouts can do the job
Start by listing the colors used for page backgrounds, body text, links, main action buttons, selected states, and errors. Note what each color is meant to communicate and look for cases where the same function already uses several colors. If you already have a highlighting color, consider reusing it before introducing another.
For example, suppose a pricing comparison page needs to identify a recommended plan. Try adding the word “Recommended,” changing the order of plan cards, or adjusting their spacing first. Only consider another color if the plan is still difficult to distinguish. Be clear about the goal: identifying an editorial recommendation is different from adding another clickable action.
Avoid reusing colors that already signal errors or success for decorative purposes. If red sometimes means a form error and elsewhere means a recommended product, its meaning becomes inconsistent. If a new color is justified, assign it to one defined role, such as the “Recommended” label.
Add a single accent color to a pricing table
Imagine a fictional service pricing table that already uses blue buttons. A HEX color code specifies a web color using a “#” followed by six hexadecimal digits.
Keep the page and card backgrounds white #FFFFFF with dark gray #1F2937 body text. The text/background contrast ratio is approximately 14.68:1. Every plan uses the same “Sign Up” button, with blue #1D4ED8 as its background and white #FFFFFF text. This pair has approximately 6.70:1 contrast. The purpose and color of the sign-up button stay the same even after adding an accent.
On the recommended plan’s card, add only a small label reading “Recommended.” Use a muted orange #B45309 background with white #FFFFFF text; their contrast ratio is approximately 5.02:1. The label is not a button and should not be presented as an extra clickable action. Its wording and position should be consistent so its meaning does not depend on color alone.
A brighter orange #F59E0B might be another candidate, but white #FFFFFF text on it has only approximately 2.15:1 contrast, below the minimum for normal-sized text. Dark gray #1F2937 text on the same brighter orange reaches approximately 6.83:1. Evaluate the actual text and background together instead of selecting a shade by its name or vividness.
With this approach, the additional color identifies a recommendation while the existing blue buttons continue to mean “Sign Up.” Restricting the orange to a small label usually makes the information hierarchy easier to manage than recoloring the entire pricing table.
Review contrast and where the new color will be used
Under WCAG (Web Content Accessibility Guidelines), Level AA generally requires at least 4.5:1 contrast for normal-sized text and 3:1 for large text. Visual information needed to identify interactive controls or meaningful icons generally requires at least 3:1 against adjacent colors. Check the label in its actual setting, including if it appears against a different card background.
Test the color in pricing tables, listing cards, and mobile layouts. Make sure the extra decoration does not undermine the prominence of the regular purchase button. Check that the word “Recommended” still conveys the distinction to visitors who cannot easily tell colors apart, and that the accent is not confused with existing selected or error states.
If you manage colors with CSS (Cascading Style Sheets, the language used to style web pages), name the new value for its function, such as “recommended-label-background.” Share where the color is allowed and who maintains it. If the label is removed later, you should be able to remove that specific rule without changing the rest of the website. Defining the purpose and scope before adding a color is an effective way to avoid unnecessary palette growth.
