Color Schemes for Asymmetrical Two-Column Layouts: How to Create Balance with Color

An asymmetrical two-column layout places areas of unequal width side by side. It can be useful when you want to feature a large photograph and keep a short booking panel next to it. But if both sides use equally strong colors, visitors may be unsure where to look first. The colors do not need to occupy equal amounts of space. What matters is how their visual weight works with column width, photography, and the amount of information. Let’s consider a fictional pottery workshop booking page.

Balance Visual Weight, Not Just the Width of the Two Columns

Visual weight is the extent to which an area attracts attention through features such as a dark background, a photograph, or prominent text. Imagine a wide photograph on the left and a narrow booking panel on the right. If the photograph contains many details, it may dominate the composition. One option is to give the smaller booking area a dark background so visitors can readily locate the reservation details.

Now imagine long explanatory text on the left and a short practical note on the right. The smaller side does not necessarily need a strong background. A pale surface, a heading, and appropriate spacing may distinguish it without distracting from the main explanation. There is no universal rule that the narrow column should always be dark. Judge the amount of color together with the visual density of the content.

Before adjusting colors, check the alignment of the column tops and headings. If one side is extremely crowded while the other is almost empty, changing colors alone is unlikely to resolve the imbalance.

Two Color Schemes for an Asymmetrical Pottery Workshop Page

The following column proportions are examples for a desktop layout, not fixed requirements. HEX is a color-code format consisting of a hash sign followed by six hexadecimal characters from 0–9 and A–F. A contrast ratio measures the relative luminance difference between adjacent foreground and background colors.

Example 1: A 65% Photograph and a 35% Booking Panel

Place a large pottery workshop photograph on the left. On the narrower right, group the workshop date, price, and booking button. Keep text off the photograph and place the reservation details on a solid-colored panel instead.

• Background around the photograph and the rest of the page: warm off-white ■#F7F3EC. Pair it with dark blue-gray ■#283A3E for ordinary text, giving an approximate contrast ratio of 10.76:1.
• Booking panel: deep green ■#24473F behind white ■#FFFFFF headings. The contrast ratio is approximately 10.25:1.
• Supporting information in the booking panel: pale gray-green ■#DDE7E1 on deep green ■#24473F, giving approximately 8.10:1 contrast.
• “Book a Workshop” button: a white ■#FFFFFF background with deep green ■#24473F text. Both the text-to-button contrast and the contrast between the white button and the surrounding dark panel are approximately 10.25:1.

The smaller dark panel acts as a visual landmark next to the larger photograph. However, if the photograph itself is dark and vivid, both sides may compete for attention. Adjust the photograph or the booking panel width rather than assuming this treatment will always balance the page.

Example 2: 70% Main Explanation and 30% Supporting Information

When the left side contains the workshop description and a step-by-step explanation, keep that wide reading area on warm off-white ■#F7F3EC with dark blue-gray ■#283A3E text. The contrast ratio is approximately 10.76:1.

• Right-hand supporting area: pale sage green ■#E8EEE7, with headings in deep green ■#24473F. The heading-to-background contrast ratio is approximately 8.70:1.
• Supporting body copy: dark blue-gray ■#283A3E on the pale sage green ■#E8EEE7 background, giving approximately 10.09:1 contrast.
• If the supporting area needs a booking button, use a muted reddish-brown ■#954B36 background with white ■#FFFFFF text. Text-to-button contrast is approximately 6.29:1; the button surface contrasts with the pale supporting background at approximately 5.34:1.

The restrained supporting area distinguishes practical details from the long explanation. Reserve the stronger button color for a primary action rather than spreading it across unrelated elements. These two layouts are alternative arrangements for different content priorities, not treatments that must both be used at once.

Keep the Reading Order Clear When the Columns Stack on Mobile

The 65:35 and 70:30 proportions are starting examples, not guaranteed ideal ratios. If the text wraps awkwardly or the booking panel becomes cramped, prioritize usable content widths rather than preserving the numerical split. Leave room between the columns and identify their purposes through headings and labels, not the background-color difference alone.

On phones, the side-by-side areas will often stack vertically. A large photograph placed first may push the date and booking button far down the page, so check the mobile content order. Each photograph has different brightness and colors. If text is placed over an image, test the actual foreground/background combination instead of relying on contrast measurements for a solid color.

Under Level AA of WCAG (Web Content Accessibility Guidelines), normal-sized text generally needs a contrast ratio of at least 4.5:1 against its background, and large text needs at least 3:1. Visual information necessary to identify controls and their states may also require 3:1 contrast against adjacent colors. The example ratios here are calculated for opaque, solid color pairs. Review not only the balance of the two sides, but also the visibility of text and buttons and the indicator shown when a control receives keyboard focus.
