Summer Cosmos vs RAL 520-1
Where Summer Cosmos belongs to Cloverdale Paint's range, RAL 520-1 is a RAL Effect color. These are both pinks, so the question isn't which hue to choose — it's where within pink to land. They have nearly identical light reflectance values (71 vs 72), so they'll read as similarly Light in most lighting conditions. At ΔE 2.2, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Summer Cosmos vs RAL 520-1 in Real Spaces

Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
