How to Refine a Dashboard Color Scheme | Tips for Showing Information Priority Through Color

A dashboard brings sales figures, order counts, and other operational data into one management screen. When every card uses a strong color, the information needing immediate attention becomes harder to find. This guide shows how to organize key numbers, actionable alerts, and supporting data using a small set of purposeful colors.

Decide what matters before assigning colors

First, sort information into three groups: items requiring action now, core measures checked every day, and supporting details viewed when needed. On an order dashboard, shipping delays may require action, today’s order count is a core measure, and a comparison with last week supplies context. The order of importance depends on the work, so a color name alone should never determine priority.

A KPI (key performance indicator) is an important measure used to assess progress toward a goal. Not all KPIs need identical size or emphasis. Give the most useful number a prominent location, larger type, and sufficient space; use color to reinforce that hierarchy. Place alerts in a distinct area and explain the problem in words.

Use restrained common colors for the page surface and ordinary cards, reserving stronger accents for selected key figures and warnings. Where color alone does not separate cards clearly, use spacing, headings, and appropriate borders. A consistent reading order generally helps more than adding extra hues.

Example palette for an e-commerce order dashboard

Consider a fictional e-commerce management screen. Set the page background to pale blue-gray ■#F4F7F9, regular cards to white ■#FFFFFF, and headings and key figures to dark blue-gray ■#263445. The calculated contrast ratio of this text against the page background is about 11.76:1 and against the white cards about 12.65:1.

If today’s order count is the main KPI, give only that card a pale blue ■#EAF3F8 surface. Show its number in deep blue ■#205D81 for a contrast ratio of about 6.34:1. A heading in dark blue-gray ■#263445 has a ratio of about 11.25:1 against the same surface. The main figure can stand out through scale and position without a vividly colored card.

For an alert such as ‘Needs attention: 6 delayed shipments,’ combine a soft reddish background ■#FFF1E9 with dark reddish-brown ■#9A3E28 text. Their contrast ratio is about 6.15:1. Do not use color as the sole indication of urgency: include the ‘Needs attention’ label, the number of cases, and an action to view details. Avoid coloring ordinary order counts red as well, since that would dilute the warning distinction.

In a comparison chart, draw this week’s series in blue ■#205D81 and last week’s series in gray ■#687886. Against a white ■#FFFFFF plot background, their contrast ratios are about 7.13:1 and 4.55:1 respectively. Distinguish the lines with solid versus dashed patterns and direct ‘This week’ and ‘Last week’ labels, not color alone. Supporting text in gray ■#556779 on white ■#FFFFFF has about 5.83:1 contrast.

Check text, meaningful graphics, and interaction states

White ■#FFFFFF cards and the overall pale ■#F4F7F9 background are close in brightness, so do not rely on that subtle difference to identify interactive cards. If a card can be selected or opened, make its purpose clear through its label, boundary, and interaction feedback. Show selected filters with wording as well as visual styling.

WCAG (Web Content Accessibility Guidelines) 2.2 Level AA, a defined accessibility conformance level, requires at least 4.5:1 contrast for ordinary text and 3:1 for qualifying large text. Meaningful chart lines and visual states required to identify or operate controls generally need at least 3:1 contrast against adjacent colors. All figures above are calculated for the specified opaque color pairs.

Finally, verify that important alerts and core metrics remain easy to find on narrower screens. HueRoll lets you enter HEX codes (hexadecimal color notation), explore tonal variations and palette candidates, and compare the selected color with white or black. It does not automatically check arbitrary pairs or determine Level AA compliance, so validate the actual adjacent colors separately.
