I’ve been building a few color and image-related tools with a focus on ease of use, solid UI/UX, and correctness as a hobby project.
What makes these different from other online tools? Very often I needed free, simple, yet powerful utilities for these little tasks and couldn’t find anything that fit, so I ended up building them myself (100% client-side, no sign-ups required!)
Color Palette Generator: Uses the OKLCH color space (instead of RGB) to generate perceptually the most distinct colors for a given scheme. It also includes sequential palettes and palette generation from an image for convenience.
Smart Color Replacer: Uses HSV-based fuzzy matching, supports multiple input-output color pairs (something I couldn’t find elsewhere), and preserves original highlights and shadows by replacing only hue. It also includes a “magnetic lasso”-style tool that snaps selection vertices to detected object boundaries (not perfect yet - I’m working on additional selection modes) to limit replacements to specific areas.
Color Mixer:A pretty simple mathematical Color averager, but allows you to input colors in multiple spaces (just write anything in the textbox, or 'bulk' copy and paste!), and adjust input and output colors quickly by clicking on the swatch.
Image Blender: Fast, simple, no frills client-side image blending. Change opacity if you need.
I’d love to hear your kind suggestions or feedback!
