How this works in your browser
The output is a standard CSS gradient function with your stops, and everything renders live in the browser as you adjust it. Smoothen addresses a real limitation rather than a cosmetic one: CSS interpolates between adjacent stops through a straight line in colour space, and between hues that sit far apart that line passes through desaturated territory, producing the grey band people notice between complementary colours. Inserting additional computed stops steers the path around it. Doing that by adding plain colour stops rather than using newer interpolation syntax is deliberate, since the result works in every browser at the cost of a longer declaration.

Frequently asked questions
Can I use more than two colors?
Yes, click the + swatch to add as many color stops as you want, or remove one by hovering it and clicking the × once you have more than two.
What does Smoothen do?
It inserts extra interpolated color stops between each pair of colors you picked, so the transition looks less abrupt across a big hue jump - the CSS output gets longer, but works in every browser since it's just more plain color stops, not a newer interpolation syntax.
What does Animate do?
It pans the gradient across an oversized background on a loop, giving a moving/shifting effect - toggle it off any time.
Can I save a gradient and come back to it later?
Yes, use Export to download your current colors, type and angle as a small JSON file, then Import that file later to load it back in.
What CSS property does it output?
A ready-to-use background declaration for whichever type you picked - linear-gradient(), radial-gradient() or conic-gradient() - plus a Tailwind arbitrary-value class on the Tailwind tab.
Why does my gradient go muddy grey in the middle?
Because interpolation runs through the shortest path in colour space, and between two hues on opposite sides of the wheel that path passes through desaturated grey. Blue to orange is the classic case. Adding a saturated intermediate stop, or turning on Smoothen, routes the transition around the dead zone instead of through it.
Does a gradient hurt page performance?
No, and it is one of the better trades available. A gradient is a few dozen characters of CSS the browser paints directly, replacing an image that would cost a network request and a download. Gradients also scale to any size without going blurry, which no background image manages.
Will text stay readable on top of a gradient?
Not automatically, and this is where gradients cause accessibility problems. Contrast must hold against every part of the gradient a letter passes over, not just the average. Check the lightest and darkest stops separately with our contrast checker, or add a semi-transparent overlay behind the text.
When should I use radial or conic?
Radial for a spotlight or glow effect emanating from a point, and for soft backgrounds behind centred content. Conic for pie-chart-like sweeps and colour wheels, where the angle around a centre is what varies. Linear covers the great majority of everyday use.
