RGB Color Model Examples for Kids: Coloring Shapes in Code

📚 Quick Study Guide

• 🔴 RGB stands for Red, Green, and Blue. These are the primary colors of light that computers use to create all other colors.
• 🔢 Each color (Red, Green, Blue) is represented by a number from 0 to 255. 0 means none of that color, and 255 means the maximum amount.
• 🎨 By mixing different amounts of Red, Green, and Blue, you can create millions of different colors! For example, (255, 0, 0) is pure Red, (0, 255, 0) is pure Green, and (0, 0, 255) is pure Blue.
• 💡 To make a color lighter, increase the values of Red, Green, and Blue. To make it darker, decrease them.
• 🖥️ In code, you usually specify RGB colors like this: `rgb(red_value, green_value, blue_value)`, where `red_value`, `green_value`, and `blue_value` are numbers between 0 and 255.
• 🌈 Mixing all three colors at their maximum value (255, 255, 255) creates white, and setting them all to 0 (0, 0, 0) creates black.
