This blog post draft focuses on the exercise (often assigned as Exercise 7.1.3 or 2.3.5) found in various CodeHS Computer Science courses .
In standard programming, the intensity of each color channel is represented by an integer ranging from .
function start() // Create a rectangle var rect = new Rectangle(200, 100); rect.setPosition(getWidth()/2 - 100, getHeight()/2 - 50);

: Each strip must display a slightly different shade, often achieved by incrementally changing one or more of the RGB values in a loop.
// Bad Practice ball1.setColor(new Color(41, 128, 185)); ball2.setColor(new Color(41, 128, 185)); // Best Practice var COBALT_BLUE = new Color(41, 128, 185); ball1.setColor(COBALT_BLUE); ball2.setColor(COBALT_BLUE); Use code with caution. Contrast and Accessibility
When working on CodeHS assignments, you are often asked to color backgrounds, text, or shapes. Here are some of the most commonly needed color codes (best answers) to keep in your toolkit: Primary and Secondary Colors rgb(255, 255, 0) Cyan: rgb(0, 255, 255) Magenta: rgb(255, 0, 255) Shades and Tones Light Gray: rgb(211, 211, 211) Dark Gray: rgb(169, 169, 169) Dark Blue (Classic): rgb(0, 0, 139) Popular Pastel/Modern Colors Sky Blue: rgb(135, 206, 235) Salmon: rgb(250, 128, 114) Light Green: rgb(144, 238, 144) 3.

One of the most common follow-up assignments is "5.7.5 Making Yellow." In this lesson, the CodeHS curriculum shows you a pixel with Red ( FF0000 ) and Green ( 00FF00 ) and asks you to add the Yellow pixel. The answer is to use the combination of Red and Green: FFFF00 .
CodeHS exercises often ask for variations of a color, such as "a darker shade of blue" or "a pastel pink."
