Practical advice
#2563EB reaches about 5.9:1 and #1E3A8A about 10:1. On dark backgrounds, use lighter blues such as #60A5FA or #93C5FD rather than deep navy, which can blend into the surface.- Blue is safe, but safe is not memorable — a distinctive variant is essential for brand differentiation.
- Pair blue with warm accents — orange, coral or amber — for stronger visual interest.
- Use different shades for different roles: light blues for surfaces, mid blues for actions, deep blues for text.
