Why Does a Color Scheme Look Cluttered? Tips for Organizing Web Design
A website can feel visually cluttered even when you have not intentionally added many colors. The problem may be that information with different priorities—such as event hours, location, and important instructions—is presented inside equally prominent colored blocks. Using a science museum’s hands-on event page, this article shows how to simplify section backgrounds and make headings, text, and registration controls follow a clear hierarchy.
Clutter can come from colored sections that conflict with information priority
Imagine an event page with a large yellow background #F7DA7C, a pale lavender panel #EADFF6 for the schedule, a light aqua panel #DDF5F3 for the venue, and a pale pink panel #F6DCE4 for what to bring. Each color could work well by itself. But when the backgrounds keep changing, visitors may struggle to identify where they should start reading. If both essential details and secondary notes receive the same prominent colored heading strips, the visual hierarchy becomes unclear.
Rather than counting colors, check the size of colored areas, which colors touch each other, and what each block is supposed to communicate. Divide the page into an event overview, time and location, things to bring and cautions, and registration. Decide which information should be seen first. Use headings and spacing to establish major sections, and reserve additional background colors for specific information that benefits from being grouped or highlighted.
Actual states, such as “Fully booked” or “Registration closed,” are different from decorative color choices. Write the status in words so its meaning does not depend on color alone. Using many colors is not inherently wrong; the question is whether color changes interrupt the intended reading order.
Organize a science museum event page by background, time, cautions, and registration
For the revised page, use pale blue-gray #F4F6F7 as the overall background and white cards #FFFFFF for the overview and location details. Choose dark blue-gray #203644 for headings and a slightly softer dark gray-blue #374B58 for explanations. The following palette assigns a clear role to each HEX (hexadecimal web color) code.
| Where the color is used | Color and HEX code | Purpose |
|---|---|---|
| Overall page | Pale blue-gray #F4F6F7 | One common background for the information |
| Overview and venue cards | White #FFFFFF | Groups information of the same kind |
| Card headings | Dark blue-gray #203644 | Marks the beginning of each topic |
| Body text | Dark gray-blue #374B58 | Describes the location, duration, and details |
| Event time background | Pale blue #E9F2F5 | Highlights only the time in a small area |
| Event time text | Deep blue #215F79 | Makes the time distinct from its background |
| What-to-bring and caution background | Pale warm yellow #FFF0D3 | Groups important supporting instructions |
| Caution text | Dark brown #694A20 | Presents instructions clearly |
| Registration button | Deep blue-green #165C70 | Uses one recognizable color for the main action |
| Button text | White #FFFFFF | Pairs with the dark button background |
| Card borders | Blue-gray #75818B | Defines the outline of white cards |
Arrange the page so visitors move from the overview to the time and venue, check what to bring, and then reach the “Register for the event” button. Use a small pale blue area #E9F2F5 only around the event time. Put packing instructions in a separate pale warm yellow area #FFF0D3. Instead of giving every section its own broad colored background, apply color only to the information that needs that distinction. Although the schedule and caution use different surfaces, keep the order of headings, details, and actions consistent.
Check contrast between neighboring colors after reorganizing the page
A contrast ratio measures the difference in relative luminance between two colors, such as text and its background. On the white cards #FFFFFF, the dark heading #203644 has a contrast ratio of approximately 12.56:1 and body text #374B58 reaches about 9.09:1. Deep blue time text #215F79 against pale blue #E9F2F5 reaches about 6.21:1. Dark brown caution text #694A20 against pale warm yellow #FFF0D3 reaches about 7.17:1. The white button label #FFFFFF against deep blue-green #165C70 reaches about 7.50:1.
In contrast, light gray text #8A9CA8 on white #FFFFFF reaches only about 2.84:1, which is insufficient for normal-sized text. The Web Content Accessibility Guidelines (WCAG) 2.2 generally require at least 4.5:1 contrast for normal text and 3:1 for large text. Do not make supplementary information so pale that it becomes difficult to read; use spacing and grouping to communicate its lower priority instead.
The white cards #FFFFFF and pale blue-gray page #F4F6F7 have only about 1.08:1 contrast. If a distinct outline is necessary, add blue-gray borders #75818B. The border contrasts with the white card #FFFFFF at about 3.99:1 and with the outer background #F4F6F7 at about 3.68:1. Essential non-text indicators in a user interface (UI) generally need a contrast ratio of at least 3:1 against adjacent colors. The registration button’s deep blue-green #165C70 also contrasts with the page background #F4F6F7 at about 6.92:1; keep the visible “Register for the event” label instead of relying on color alone.
Finally, check the mobile layout to see whether visitors can follow the event date, venue, what-to-bring information, and registration in that order. HueRoll lets you select a color from its 256-color palette, explore related colors and palette suggestions, and save candidates in My Palette. Its contrast panel compares the selected color against white and black only; it cannot automatically compare arbitrary color pairs or assign WCAG AA/AAA outcomes. The paired-color contrast ratios used here were calculated separately.
