How do I make a color bucket tool.

Hello guys, I am making a coloring book type of game and I want to make a color bucket tool. Can anyone help me how can I make the color bucket tool.

There is a Color Picker plugin, but I don't know how it works.

If you have a small number of colors, you can just make them with sprites - red sprite, blue sprite etc.

If you need a full palette, you might need to use Canvas plugin to read pixel color:

Is there any other way without adding plugin. And thanks for reply

Oh, wait, you mean Bucket tool to fill a shape with color?

I thought about a "picker" tool to select color.

I think Canvas plugin is your best option.

Thx
