Coluris in a nutshell

• Coluris lets you color line-art images directly in your browser.
• Use any picture from the Gallery, or upload your own by pasting, dragging and dropping, opening a file, or taking a photo.
• It works smoothly on Desktop, Mobile, and Tablet even when using digital pencils.
• You can fill entire areas with the Fill tool, or color freehand with the Brush tool.

Quick tips

1. Use the scroll wheel in your mouse or pitch gesture to zoom in and out the image.
2. Long press the image to use Crop and Levels tools on it.
3. Select a color or pattern and paint the areas you want to change.
4. Use Undo/Redo to refine quickly and export when you are happy.

About the author

I’m a primary school teacher in Spain.

I like using colouring tools with my pupils in early ICT lessons because they help them learn how to use the mouse and develop fine motor skills.

Since I couldn’t find a web app that suited my needs, I decided to build my own.

I hope you find it usefull.
