means the color channel is at maximum brightness (100% intensity). The Math Behind 255
h1 color: rgb(255, 0, 0); /* This turns the text Red */
In programming, each color channel (R, G, and B) is represented by an integer ranging from 0 to 255 . means the channel is completely turned off (no light). 255 means the channel is at maximum intensity (full light). Mixing Core Colors
: Each color channel (Red, Green, Blue) uses a value between 0 and 255 . 0 : No light (darkest). 255 : Full intensity (brightest).

Think back to the concept of additive color mixing: Red light + Green light = Yellow light. Therefore, to create yellow, you turn the red and green channels fully on, and the blue channel completely off.
RGB stands for . It’s an additive color model used in digital displays (monitors, phones, TVs).
If an exercise allows creative freedom, use an online RGB color picker tool. You can visually select a color, copy the exact generated RGB triplet, and paste it directly into your CodeHS program.
To truly become an expert, it's not enough to just copy the "right" answer. The best way to master RGB on CodeHS is to understand the concepts thoroughly and practice applying them. Here are some strategies to help you get there: means the color channel is at maximum brightness

As he hit 'Run,' the rectangles shifted. The harsh blocks of color blended into a gradient that looked less like a math problem and more like a memory. Leo realized then that coding wasn't just about getting the logic right; it was about finding the specific frequency where the turned into He clicked submit, the "Congratulations" green — (0, 255, 0) — finally appearing on his screen. hex-to-RGB conversion for your own project?
