indigo

A dark purple facade color with a strong blue component, represented by the reference hex triplet 4B0081.

Indigo is a dark shade of purple, between purple and blue on the color scale. It is not a common color for natural facade materials, but is used occasionally as a color for paint, tiles, or bricks.

Hex triplet: 4B0081

The bluish tint distinguishes indigo from the redder grape shade. Paint, brick, and tile are examples rather than required materials. The hex triplet is a comparison sample for a range of similar facade colors, rather than an exact-match requirement.
