I agree with cat_ky.

Also, I kept something from Lori Sawaya that might help. She said...

"I have a rule of thumb. It goes like this. As long as two colors of white have a difference of at least 0.20 in Chroma, neither will make the other look dirty or dingy. AND as long as you think the two colors go together, look pretty next to each other then you have yourself a white color scheme that works."

If it's any help, I see Westhighland White has a chroma of .79. Extra White appears to be .32. Not sure about High Reflective White, but am guessing there's much more of a difference.

Thank you guys!!

I think I'll do everything in Westhighland. Walls, trim doors and even ceiling..?

I also like Pure White with Westhighland White. I use matte on the walls, flat on the ceiling and satin on trim.

High Reflective White isn't available in all SW products. So, it's a good idea to verify that you can get it mixed in the product you want to use.

If you do the ceiling, use a flat paint.

Thank you all! I really appreciate it.
Last question, do you all think the sw Westhighland white will look ok with brown/red laminate? Didn't choose the flooring, came with the house. I think this paint color looks nice haha but want you all's opinion.
My couches are a darkish gray, rug has light blues, teal/green, creams. I want to stick with those colors. Love them. Have white curtains also.

I love WHW with wood tones - all wood tones. Fresh, warm and pretty is what you'll end up with.

What about linens with WHW walls? Would you do white, ivory, cream, or pale grey?
