Startup Tech Palette

Using this palette

Indigo-violet has become the default 'modern tech' signal for a reason — it reads as more distinctive than corporate blue while still feeling controlled rather than playful, and #4F46E5 in particular is close to what a large share of current SaaS products actually ship. The addition here is #22D3EE, a cyan that's hue-distant enough from the indigo family to work as a genuine CTA color rather than just a lighter shade of the same thing — use it sparingly for the one button per screen you actually want clicked. #1E1B4B works as a dark-mode base; #818CF8 is the safest 'brand color but lighter' for hover states without losing hue identity.
