Features
As many colors as you like
Add, reorder, duplicate, and delete color stops. Choose each one by dragging on a full saturation and brightness field, or type an exact hex value on a keypad that only offers hex digits.
Four gradient styles
Linear along any angle, radial rings from a point you drag, an angular sweep, or a wavy ramp with adjustable depth and frequency.
Real transparency
Every color has its own opacity, and exports are PNGs, so transparent areas stay transparent.
Smooth, not banded
Large gradients across only 256 shades per channel normally show visible stair-stepping. Prismatic renders in high precision and dithers on the way out, so what you save stays smooth even on a big display. What you see while editing is what gets written to the file — the preview and the export share one renderer.
Any size
Your screen's exact pixels by default, plus iPhone, iPad, square, HD, 4K, and 5K presets, or type your own up to 8192 pixels.
