#003aff - C64 Blue color

An intense, saturated electric blue with a vivid, slightly cool undertone.

It feels modern, energetic and tech-forward, excellent for call-to-action buttons, hyperlinks, branding, and accents that need high visibility against pale backgrounds. Pairs beautifully with white, soft grays, warm corals or muted oranges to create dynamic contrast and approachable clarity.
