Gradient Comparison Tool

Why This Tool Exists

Modern AI and tech products often use vivid gradients as visual identifiers - but not all gradients are created equal.

The traditional RGB colour space can produce muddy, desaturated midpoints when interpolating between colours. OKLCH (a perceptually uniform colour space) maintains vibrancy throughout the gradient, producing the crisp, professional results you see in products like ChatGPT, Anthropic Claude, and other AI interfaces.

This tool lets you compare RGB and OKLCH gradients side-by-side, helping designers and developers choose the right approach for their brand identity.

Practical Applications

Brand Identity - Ensuring your AI product’s gradient looks professional
Web Design - Choosing between CSS gradient methods
Technical Understanding - Seeing the difference between colour interpolation methods

We originally built this tool for a client demonstration and found it so useful that we’ve integrated these principles into our own site design and custom Zendesk applications. You’ll see OKLCH gradients used throughout the Deltastring brand and in the solutions we deliver to clients.

RGB Linear Gradient

#eb7824 (orange) → #111d30 (dark blue)

Blended Gradient

#eb7824 (orange) → #111d30 (dark blue)

OKLCH Gradient

#eb7824 (orange) → #111d30 (dark blue)

Note: The RGB gradient interpolates linearly through RGB space (straight line). The OKLCH gradient interpolates through perceptual colour space, taking the shorter arc around the hue wheel. The blended gradient averages both approaches at each point. OKLCH may not be supported in all browsers.
