repaint the world
your own way


Tweakolor is a little painting app for all ages enabling you to experiment with light and color.

You start from the grayscale image and then paint over using the original color or the new color. The brush with soft edges makes your strokes look natural and unspoiled. The app is fast and responsive to the touch. With unique RCND (Rotate Canvas Not Device) drawing system, you have the full control of the canvas scale, position and rotation so you can easily repaint complex objects with subpixel precision. Once tried, you will have a hankering for RCND be part of your other painting apps!

There are several filters for tweaking lightness, colorfulness, balance, and… queerness. All filters are non-destructive and its parameters can be fine-tuned at any stage. You do not need to repeat the modify/apply/check/rollback steps to find the best filter settings. Instead, you modify filter parameters and instantly see the result in full screen in real time.

The app is children friendly and can be configured to allow small kids to play safely.
