chart series palette · #203 · #99

Series color comes from the band ramp

The dashboard's SENSOR_COLORS are generic blues and purples that aren't in the token ramp, so a multi-probe chart reads as a different palette than the rest of Sprout. Swap them for a sanctioned categorical set drawn from the band ramp — one palette, end to end.

{{ c.hex }} {{ c.token }} {{ c.name }}
