Warning: This project is not revolutionary in any way, but rather I figured out Scratch's pen. When you set a pen color, you may use the color sliders or use a variable in place of the color. You can type in any number, and it would seemingly pump out a mysterious number - but I know the exact formula behind it. A typical set of RGB sliders has three sliders, each representing the intensity of a color from 0 to 255, making 256 possible values. In Scratch, Blue is prioritized before any other color (let me explain). The values 0 through 255 when entered into the project will result in a different shade of blue, or full black if 0 is entered. But when 256 is entered, it seemingly goes back to black, but actually it adds one point to the Green slider and resets the Blue slider. Basically, for every time Blue surpasses 255, Green increases by one and Blue is reset. What about when both Green and Blue sliders are at 255, resulting in a teal color, and Blue goes up by one? Well, Green naturally increases, but it surpasses 255. So both Green and Blue are reset and Red increases by 1. You will discover that the value 65536 will give you a very dark red with the RGB value (1, 0, 0). Because of the way Scratch prioritizes cool colors over warmer colors, a lot more values need to be surpassed to reach even this dark red. So here is the formula I made up to convert from Scratch Color Notation to RGB Color Notation: RGB = Red, Green, Blue (Respectively) S = Scratch Color Notation Converting from S to RGB: R = floor(S / 65536) G = floor((S - (R * 65536)) / 256) B = ((S - (R * 65536)) - (G * 256)) Converting from RGB to S: S = ((R * 65536) + (G * 256) + B) This is what I found through trial and error, and I know other people may have found this out themselves - but this is just something I decided to do on my free time, and I am wondering if it will be helpful at all in any of your projects!
