RAL 340-1 vs Chaise Mauve in Real Spaces
1 real room side by side. RAL 340-1 and Chaise Mauve are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Chaise Mauve has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Before committing to either color, test physical samples in your own space under the light you actually live with.
