GRADIENT STUDIO

Build the transition, then test where it will be used.

Choose the gradient type, arrange the color stops, compare the midpoint behavior, and check text placement before saving or exporting.

STEP 2 · REVIEW

Check the gradient in context

Switch views to expose uneven midpoints, weak text placement, or distracting transitions.

CSS GRADIENT GUIDE
Build a CSS gradient and inspect what happens between the color stops.
A gradient is more than two endpoint colors. Direction, stop positions, gradient type, interpolation space, and the content placed on top of the result can all change how the transition behaves. HexCheck keeps those decisions visible while you build linear, radial, or conic gradients.
Choose the structure before polishing the colors
Linear gradients move along an axis, radial gradients expand from a center or focal region, and conic gradients rotate colors around a point. Stop positions control where each specified color takes effect and how much space is available for the transition between them.
Adding more stops can give precise control, but every stop also adds another transition to evaluate. Start with the smallest structure that produces the effect you need, then refine positions or colors.
Interpolation changes the colors in the middle
The same endpoints can produce visibly different midpoint colors depending on the interpolation space. sRGB interpolation follows familiar encoded RGB behavior, while perceptual spaces such as OKLab and OKLCH can produce transitions that feel more even in lightness or hue.
If text or controls will sit over a gradient, test the placement rather than checking only the endpoint colors. The least-contrasting region may occur somewhere between stops.
Common questions
What is the difference between linear, radial, and conic gradients?
Linear gradients transition along a direction, radial gradients transition outward from a center or focal shape, and conic gradients transition around a center angle.
Why does OKLCH interpolation look different from sRGB?
They interpolate color using different coordinates. OKLCH separates perceptual lightness, chroma, and hue, so the path between the same endpoints can travel through different intermediate colors.
Can text pass contrast at one part of a gradient and fail at another?
Yes. A gradient contains many intermediate colors, so text contrast can change continuously across its background. Test the actual placement and the weakest region.
