๐ Topic Summary
The RGB color model is a way of creating colors using different amounts of Red, Green, and Blue light. By mixing these three primary colors, we can create a huge range of different colors that you see on computer screens, TVs, and phones. Each color (Red, Green, Blue) is assigned a value, usually between 0 and 255, which determines how bright that color is. When all three colors are set to 0, you get black. When all three are set to 255, you get white. Everything else is a mix in between!
Think of it like mixing paint, but with light! ๐จ
