Primary colour carries trust
Blue is common in technology and education sites because it reads as stable and works behind large amounts of text. White space keeps dense course parameters and job labels legible.
Accent colour stays scarce
Orange and red are reserved for prices, buttons and limited offers. The less often an accent appears, the more precisely it points to the next step.
Hierarchy before decoration
Headline, course cards, labelled roles, classroom photography and student stories follow results, path, evidence, reassurance. Decoration is deliberately kept low so evidence remains the focus.
