Scratch Colour Picker - Click the Flag to kick it off. Adjust Sliders to select a Colour (& its opposite inside it) to be drawn. You can also click on a Colour in the Colour Wheel to select it.
Created by @gregatku for use in Coding Classes for Kids Unlimited. This Project uses the Pen to draw a Big Dot in the colour selected using the Sliders (or for colour by clicking on the appropriate spot on the Colour Wheel), and a smaller one inside it in the opposite or complementary colour. The code for displaying the Lightness Bar is an optional extra.
