Press the green flag. This project, given a hue, saturation and brightness, will completely accurately recreate the colour given in the scratch editor using graphic effects. Brightness is done using a ghost effect on a black background, so there are some limitations. To get around the scratch's "brightness" effect having some unintended effects, the colour value has had some operations done to it. Thanks, @Nembence . This may impact performance if you want to use it, so if you want less accuracy for higher speed, replace colour with simply hue * 2.
