Pixel Composer builds effects, animations and generated art from node graphs, so a change to one input flows through the whole result.
New ramps come hue-shifted out of the box, with light steps leaning towards yellow and dark steps leaning away from it, so you start from good shading and fine-tune from there. Click to add curve points and drag to reshape them; smooth curves never overshoot, so your shades always stay in order.
Check your work as you go:
- A hue wheel and lightness plot show every ramp in the palette at once
- Greyscale mode shows the true lightness of every colour, to check your contrast
- Preview a ramp on a sample orb or cube, or open your own PNG and see it recoloured with your palette
Shared colours let you use one outline or highlight colour across every ramp, and a colour limit (4 to 256) warns you when the palette grows too big.
Export as a .hex file, a PNG strip (1 px or 8 px per colour) or a PNG with a row per ramp, ready to load into Aseprite or any other editor. If you use Rastrivo Studio, Send to Rastrivo opens the palette there in one click and saves it as a preset.
Free, with no account, ads or tracking. Available for Windows on the Microsoft Store, with a Mac version coming soon.
Pixelmash takes high-resolution artwork - painted, photographed or rendered - and pixelizes it through a stack of layers whose settings stay editable. Change the output resolution or the palette at any point and everything downstream re-renders, which makes it a way to try pixel sizes rather than commit to one.
