Why UI Design Needs More Color Shades Than You Think

Why a small color palette isn’t enough for UI design

When we think about color in design, the first step is often choosing a palette and sticking with it.

Maybe we pick a few colors ourselves or use an online palette generator to find five shades that work well together. That can be a useful starting point, but UI design usually needs a much broader range of colors.

An interface is made up of many layers:

A small palette may look good on a moodboard, but it can quickly become limiting once you start applying it to an actual product.

A palette needs room to work

Apple is a familiar example of how subtle variations can support a consistent visual language. Across its interfaces, similar colors appear in different shades and levels of intensity depending on their purpose. Those variations help create hierarchy and depth without making the interface feel unnecessarily colorful.

This is one of the limitations of online color palette generators. They are useful for exploring combinations and finding a direction, but they are rarely complete enough for UI work. Five colors that look great next to each other don't necessarily give you everything you need to design a full interface.

Instead, it helps to treat the initial palette as a foundation. From there, you can create lighter and darker variations by adjusting brightness, saturation, and other properties. The exact number of shades depends on the project and how the colors will be used.

Start with the colors you use most

Neutral colors usually do much of the work in an interface. Grays and other neutrals are used for text, backgrounds, panels, borders, and form controls, so having around six to ten neutral shades is practical for many projects.

The goal isn't to create as many shades as possible. Too many nearly identical options can make decisions harder. You simply want enough range to create a clear hierarchy without repeatedly compromising because the shade you need doesn't exist.

The same principle applies to the rest of the palette. Your primary color will usually need lighter and darker variations, and the same may be true for accent colors. Semantic colors for states such as success, warning, error, and information also need enough flexibility to work across backgrounds, text, borders, and other components.

By building these variations early, you end up with a fixed set of colors that can be reused throughout the interface. Instead of choosing or adjusting colors every time a new component appears, you can work from a palette designed around the actual needs of the UI.

Conclusion

A good UI palette gives you enough flexibility without creating unnecessary choices. By building a considered range of neutrals, primary, accent, and semantic shades, you can keep color decisions consistent across the entire interface.
