Proud Peacock vs L366
Where Proud Peacock belongs to Dulux's range, L366 is a Tikkurila color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Proud Peacock (LRV 21) reflects noticeably more light than L366 (LRV 15), a difference of 6 points that becomes especially apparent in rooms with limited natural light. The ΔE 6.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
