StretchLearn Course
A system-first path from colour models to accessible, on-brand, print-ready palettes.
Course Overview
Move past colour-wheel intuition to a repeatable colour workflow used by working designers. You will model colour in HSL and OKLCH, build accessible palettes that pass WCAG 2.1 contrast, manage colour across RGB and CMYK, and apply colour strategically to brand and interface decisions across markets and cultures.
Learning Outcomes
Model any colour in HSL and OKLCH and convert deliberately between RGB, HEX, and CMYK
Build a complete brand palette with tints, shades, and tones using a documented stepped scale
Test every colour pairing against WCAG 2.1 contrast ratios and fix failures methodically
Apply harmony schemes (analogous, complementary, triadic, split) to real layout decisions
Account for cultural and market meaning when selecting colour for global audiences
Prepare and check colour for screen and print so it reproduces predictably across media
Curriculum Preview
Preview the course structure, see how the modules build on one another, and understand the path this program is designed to take you through.
Replace colour-wheel folklore with the physics and perception that drive every real decision: light versus pigment, the three properties of colour, and why your screen and your printer disagree.
Get fluent in the notations you actually type: HEX, RGB, HSL, and the perceptually even OKLCH. Learn when each one helps and how to convert between media without surprises.
Turn theory into deliverables: harmony schemes you can apply to layout, a documented tint-shade-tone scale, and accessible pairings proven against WCAG contrast.
Use colour to do a job: shape brand perception, respect cultural meaning across markets, and document everything so colour stays consistent everywhere it appears.
Built for Application
This program is designed around progression: focused lessons, structured modules, applied resources, assessments, and a course rhythm that turns information into usable capability.
