Palette Generator
Build colour palettes for pixel art and games — generate hue-shifted shade ramps, blend gradients, or pull colours from an image, then export .gpl, .hex, .ase or PNG. Nothing is uploaded.

Frequently Asked Questions
What is a colour ramp and why does it matter?
A ramp is an ordered set of shades of one colour, from dark to light, used to shade a single material (skin, metal, grass). Good ramps do not just change lightness — they shift hue as they go (shadows cooler, highlights warmer) and ease the saturation, which is what makes pixel art read as vivid rather than flat. This tool generates that hue-shifted ramp for you from a single base colour.
Which formats can I export?
GIMP palette (.gpl) for GIMP, Krita and Aseprite; a plain hex list (.hex) as used by Lospec and Aseprite; Adobe Swatch Exchange (.ase) for Photoshop and Illustrator; and a PNG swatch strip you can drop into any project or use as a palette texture. Everything is generated in your browser.
Can I make a palette from an existing image?
Yes. Load any image and the tool extracts a palette from it using median-cut quantization — pick how many colours you want. It is a fast way to pull a cohesive palette from reference art or a screenshot. The image is processed locally and never uploaded.
How is the shade ramp generated?
From your base colour it spreads lightness toward black and white across the number of steps you choose, shifts the hue linearly (shadows one way, highlights the other by the degrees you set), and gently reduces saturation at the extremes so the mid-tones stay punchy. You control steps, spread, hue shift and the saturation arc.
What is the difference between a shade ramp and a gradient?
A shade ramp takes one colour and derives its lighter and darker versions for shading. A gradient blends between two different colours across a number of steps. Both are one click here — use ramps for materials and gradients for transitions, skies or UI.
Can I clean up a palette?
Yes — remove duplicates, sort by hue and lightness so similar colours group together, delete individual swatches, or clear everything and start again. You can also edit any swatch by selecting it and changing its colour.
Is anything uploaded?
No. Palette building, ramp generation, image extraction and every export happen entirely in your browser. Nothing is sent to a server or stored anywhere.
