A small tutorial about using a canvas as a colorpicker.
I use a
- canvas,
- color utilities
- label
- button
- notifier
I made a screenshot of one of the palettes on this page.
https://paulwratt.github.io/programmers-palettes/programmers-palettes.html
I put the screenshot as a background image of the canvas.
I used these blocks.
When i drag my finger over the palette the label shows the hexvalue of the color.
You can make the canvas as big as you want or show it in a custom dialog.
In this case the canvas is put inside a vertical arrangement.
So with a few blocks you have a lot of colors you can use.
