Also Serious Gray by Sherwin Williams is very very close to the same color as Storm Cloud and the color in this picture. I found Serious gray to look a touch more grey and Storm Cloud to look a touch more blue- depending on your lighting you will know which is right!!

I have possible a similar color in my house, at the very least it could be somewhere to start. Sherwin Williams "Network Gray".

Looks more like Granite Peak-sherwin William?

I find that the color you see depends on your computer monitor. Get a few color fans Sherwin Williams , Benjamin Moore etc. see a color that looks nice on your monitor find a Cole that matches it. Looks like pewter gray By BM on my monitor .

It's not possible to color match on a computer screen - I made that mistake once.

While it's true that the appearance of color on a monitor can vary based on display settings, view angle, environmental factors, etc., the underlying RGB color model of an app is the same no matter how your specific monitor "interprets" those colors.

That's why you can you a tool like www.painthunter.com to take the subjective eyeballing out of color matching.
