Blues read as cooler and often darker than they measure, so don’t assume white text is automatically safe — check the actual ratio. Use #6A9AB8 ( hsl(204, 37%, 57%)) directly in CSS or your design tool — for print, ask your printer for the closest CMYK or Pantone match before production.
Slate Blue is most often paired with Dusty Rose. Start from #6A9AB8 in the Colortion generator and build outward from there rather than starting from scratch.
