ColorCalc
A downloadable tool
ColorCalc is an advanced palette generation and calculation tool for Aseprite 1.3.x, designed to create consistent color ramps and controlled variations from a reference row.
Main features:
- Editable reference row that automatically recalculates all derived palettes
- Derived palettes with color anchoring (any color can become the new base point)
- Real-time adjustable grid (2–9 columns, 2–8 rows)
- Color interpolation in multiple spaces: HSL, HSV, LAB, and Oklab
- Automatic generation of gradients between extremes
- Intelligent random variations to explore new palettes
- Material presets: skin, metal, vegetation, and sky
- Color harmony generation: complementary, analogous, triadic, tetradic, and split-complementary
- Advanced Hue Shift options and saturation preservation based on brightness
- Global color temperature and contrast adjustments
- Direct integration with Aseprite (left/right click for front and background color)
- Shades view per row for quick color selection
Designed for artists who want control, consistency, and speed when working with color, without losing creative freedom.

Is there a video guide on how this works?
There is no video guide. I always try to make the tools as intuitive as possible, but if you have any questions, please let me know.
This tool starts with a reference palette (there is one already in place, but you can customize it). For example, you place the colors you use for the vegetation in a drawing in the reference palette. Then, you choose another color from the derived palette to generate a new palette for a building or for the ground or whatever you need. The new palette will be equivalent to the reference palette.
It also has an “inspiration” component with random buttons (rnd) that will generate random palettes—reference or derived—so you can work with them as well.
