Hi - it isn’t worth pairing these two in the same space as there isn‘t enough contrast in chroma (degree of colour), between them.

You would be better choosing one and just changing its sheen for the trim.

The CC-20 Decorator's White webpage does show OC-65 Chantilly Lace as a matching color. Color samples are 50% off through May 13 so you could get a sample of each and see how they look together.

Next to Chantilly Lace, Decorator’s White is likely to appear a very pale grey. 🌿

Well, the BM webpage says, "A touch of cool gray gives this go-to white sleek, stylish appeal."

The proximity to a higher value white. like Chantilly Lace can accentuate any sense of greyness in Decorator’s White.

But in a well-balanced, well well-lit room, where Decorator’s White is the only very light near neutral white, it can read ’just white’. Lighting & context are everything.
