Warmer mid purple-blue for secondary accents
About Warm Blue
Warm Blue looks like a purple that decided to take the blue train, not the purple one. It's medium-depth and noticeably warmer than the cooler, heavier Arcane Brew, with a cleaner read than Savoy Blue. Compared to Royal Blue, it keeps more purple in the undertone, so it doesn't feel like a straight "blue first" primary.
I use it when I need a focus state or link color that feels confident without going cold, especially in dashboards and finance apps where those accents have to stay legible but not sterile. It also works well in creator platforms and learning interfaces for buttons, hover states, and callout headers on bright surfaces. In motion mockups it behaves like the one you reach for when you want interactivity to pop without leaning neon.
Pair it with soft lilacs, warm grays, or pale cream. If you place it beside very cool steel tones, it can start to feel slightly "purplish-blue" and pull attention from your main hierarchy.
