How Should You Choose Website Background Colors? How to Pick Colors That Are Easy to Read and See

TIPS

Choosing a website background color becomes easier when you start with what people need to read and how much information the page contains, rather than personal color preference alone. A text-heavy guide and a photography-led page may need different surfaces. Using the visitor information page of a science museum, this article compares three alternatives—a light neutral, pale blue-gray, and deep blue-gray—and explains how to choose text and action colors alongside each one.

Start with Information Length, Text, and Interactive Elements

List the important content before deciding on a background. A museum page might contain an exhibition overview, opening information, a visit-date selector, and a ticket booking action. For longer descriptions, begin with a calm surface that permits strong lightness contrast against text. A darker background is another option for a section where large photographs lead the layout.

After choosing the surface, put actual headings, paragraphs, and supporting details onto it. A contrast ratio measures the difference in relative luminance, or lightness, between two colors. Even colors with very different hues—their general families, such as red and blue—can be difficult to distinguish if they have similar lightness. Check the lettering against the button fill and a selectable card against its surroundings as separate pairs.

Compare Three Background Color Options for a Museum Visitor Page

These are alternative designs for the same page, not a suggestion to combine all three large backgrounds at once. The values below are HEX codes, hexadecimal values used to specify colors on the web.

1. A Light Neutral Background for Information-Heavy Pages

Page background: warm off-white ■#FAF9F6. Main headings: deep blue-gray ■#214E60, with approximately 8.59:1 contrast against the page. Body text: charcoal ■#283740, providing approximately 11.66:1.
Supporting text such as opening hours: muted blue-gray ■#56636B, with approximately 5.88:1 contrast against off-white ■#FAF9F6. For the “Book tickets” button, use deep teal ■#205B52 with white text ■#FFFFFF. Label-to-button contrast is approximately 7.84:1, and the button fill contrasts with the page background ■#FAF9F6 at approximately 7.44:1.

This option puts long explanations and the order of headings first. The large surface remains restrained, while one deeper color identifies the main action.

2. Pale Blue-Gray for Choosing a Visit Date

Background of a date-selection view: pale blue-gray ■#EAF2F4. Use charcoal ■#283740 for body text, giving approximately 10.82:1 contrast, and muted blue-gray ■#56636B for supporting details, giving approximately 5.45:1.
Individual date cards: white ■#FFFFFF. White differs from the surrounding blue-gray ■#EAF2F4 by only approximately 1.13:1. If the entire card is a selectable control, add a slate-gray border ■#70818A. The border contrasts with the white card ■#FFFFFF at approximately 4.04:1 and with the pale background ■#EAF2F4 at approximately 3.56:1.

Show a selected date with the word “Selected” or a checkmark as well as a visible outline, rather than color alone. The deep teal booking button ■#205B52 also contrasts with the pale blue-gray background ■#EAF2F4 at approximately 6.91:1.

3. Deep Blue-Gray When Large Photographs Take the Lead

When exhibition photography is the focus, a deep blue-gray background ■#223442 is an option. Use near-white ■#F9FAFC for headings, with approximately 12.28:1 contrast, and pale blue-gray ■#E6EDF0 for explanations, with approximately 10.83:1. For the ticket button, use light amber ■#F0C879 with dark blue-gray lettering ■#23323B; their contrast ratio is approximately 8.32:1. The amber fill contrasts with the dark background ■#223442 at approximately 8.09:1.

Moving this same amber ■#F0C879 onto the light off-white background ■#FAF9F6 reduces the difference between the button and its surroundings to approximately 1.51:1. Revisit accent colors whenever the background changes.

Review Small Text, Essential Boundaries, and Real Viewing Conditions

For example, pale gray text ■#9AA8AE on the pale blue-gray background ■#EAF2F4 has only approximately 2.16:1 contrast, insufficient for normal-sized text. A very light line ■#DCE5E7 against a white card ■#FFFFFF provides only approximately 1.28:1. If a line is necessary to identify an interactive area, use a darker border rather than treating this weak boundary as sufficient.

For keyboard focus—the state showing which control currently receives keyboard interaction—consider a slightly offset outline around the button. A dark blue outline ■#244B73 contrasts with the light background ■#FAF9F6 at approximately 8.56:1. On the deep blue-gray background ■#223442, a pale yellow outline ■#F4DD9B provides approximately 9.56:1. Do not rely on mouse hover alone to show where keyboard users are focused.

Under WCAG 2.2 (Web Content Accessibility Guidelines) Level AA, normal-sized text generally needs at least 4.5:1 contrast with its background, while qualifying large text needs at least 3:1. Essential non-text cues used to identify a control or its state need at least 3:1 against adjacent colors. These requirements do not apply identically to every purely decorative line. Finally, check the layout on a phone, over the bright and dark areas of photographs, and wherever paragraphs wrap. Choose the background based on how well the actual visitor information can be read and used.
