Choosing the right color palette is crucial for creating an aesthetically pleasing and functional dark theme. Dark themes have risen in popularity due to their sleek look and ability to reduce eye strain in low light environments. When designing a dark theme, it’s important to select colors that complement each other and align with the desired aesthetic. This article will provide guidance on selecting colors for dark themes that are legible, accessible, and visually cohesive.
Aim for Sufficient Contrast
The most fundamental requirement for a dark theme palette is ensuring sufficient contrast between foreground and background elements. Low contrast makes a design difficult to decipher and inaccessible to users with visual impairments. The WCAG 2.0 accessibility guidelines recommend at least a 4.5:1 contrast ratio between text and background colors. When choosing dark theme colors, aim for contrasts at or above this ratio. Pure black text on a pure white background provides maximum contrast, but lower contrast dark palettes can still be legible if thoughtfully designed.
Test your colors using a color contrast checker to identify any insufficient contrast issues. Adjust colors as needed to meet minimum contrast requirements. Keep in mind that contrast needs may vary depending on font sizes, weights, and styles used in the design. Carefully evaluate contrast at different scales.
Use Darker Shades of Blue, Green and Gray
When designing a dark theme palette, shifting to darker, desaturated versions of traditional web colors is a good starting point. Deep shades of blue, green, and gray make excellent primary colors. Blue has positive associations with trust, intelligence and stability. Green is linked to nature, health, and renewal. Gray comes across as balanced and neutral.
For example, Navy blue (#03045E), forest green (#006466) and charcoal gray (#36454F) make a soothing, professional dark theme palette. Avoid going too dark with primary colors—use just dark enough values to sufficiently contrast with white text and interface elements. This will prevent a theme from feeling too dim.
Add Accent Colors Thoughtfully
Once you’ve selected main colors, consider adding one or two accent colors to add visual interest. Vibrant accent colors can energize a dark interface, but should be used sparingly to avoid clutter. Try peach (#FFCC99), gold (#FFD700), purple (#9966FF) or teal (#008080). Accent colors will stand out best on darker backgrounds.
Make sure accent colors have enough contrast from the background but don’t overpower the main palette. Use accents minimally for elements like headers, buttons, and highlights requiring extra emphasis. Too many competing colors weaken a palette. Limit accents to strategically draw attention.
Use White Space Generously
Negative space is as important as color in dark theme design. Generous use of white or near-black space provides contrast between elements and visual breathing room. Dense, crowded layouts feel oppressive with a dark palette. Boxing in content with stark white space makes it pop.
Leave plenty of padding around text. Use minimal, simplified interfaces with breathing room between buttons, menus, and other items. Clean white space prevents dark themes from feeling too heavy.

Sample Dark Theme Palettes
Here are some example color palettes following the above principles:
Professional:
| #2B2D42 | #8D99AE | #EDF2F4 |
This palette uses dark blue and gray as primary colors with an off-white accent. It has an elegant, corporate feel.
Nature Inspired:
| #2B580C | #6E7539 | #BAC964 |
Earthy green and brown shades create an organic look. The gold accent adds a sunny touch.
Minimalist:
| #252525 | #636363 | #A1A1A1 |
Subtle light and dark grays provide a clean, uncluttered look. The medium gray adds depth.
Bold:
| #372476 | #F25F5C |
Vibrant purple and red make a lively statement. Reserve bold colors for accents against dark backgrounds.
Ensure Text Legibility
With any dark theme, be sure to test text legibility thoroughly. Fonts that work on a light background may not hold up well reversed. Simpler, bold sans serif fonts tend to have the best readability on dark interfaces. Try fonts like Arial, Helvetica, or Verdana.
Text should be crisp and easy to read at both small and large sizes. Subtle text shadows can add definition on very dark backgrounds. Adjust line height and paragraph spacing as needed so blocks of text are well-spaced and comfortable to read. Use font colors with high contrast against the background.
Get User Feedback
No matter how carefully you test, don’t finalize a dark theme without getting user feedback. Display your dark palette next to a light version of the interface. Gather impressions on readability, eye strain, and aesthetic appeal.
Ask users to complete realistic tasks and observe where they struggle. Check color perceptions for users with color blindness. Revise any colors that prove difficult based on feedback. User testing helps refine the palette for accessibility and visual cohesion.
Allow User Customization
For broader accessibility, include settings allowing users to customize the interface. Offer font size adjustments, theming options, and ways to override colors. Provide sufficient contrast ratios, but allow changing foreground and background colors. Users have varying vision needs. Customization empowers diverse users.
Re-Evaluate with Design Changes
Treat your color palette as a living document. As you make design changes, re-check that foreground and background colors maintain sufficient contrast ratios. Monitor that accent colors remain balanced.
Periodically retest the palette with users in case issues arise. Refine color values to address new visual hierarchies and layout patterns. Adapt the palette as needed while preserving your core vision.
Conclusion
Dark themes require careful, deliberate color choices to craft an interface that’s usable, accessible, and visually appealing. Keep these tips in mind when selecting your palette:
– Use darker, desaturated cool tones like blue, green and gray as primary colors
– Add minimal vibrant accent colors for visual interest
– Ensure high contrast between foreground and background elements
– Provide generous negative space and minimalist layouts
– Test extensively with users and allow customization
– Re-evaluate with design changes to maintain accessibility
A thoughtfully constructed dark theme palette lets content take the spotlight while reducing visual fatigue. The right colors can make for an elegant, functional user experience.
