Color Matching

I have a client that wants me to put a blue wash over mono images and blend them together to what they like. My question is if I get a set of color numbers from client. How can I make this color in Resolve? I've never done it before, and I've searched the web and manual. Here are the numbers. From the man who still types with 2 fingers. I am using the color generator off and keep moving it and resampling, touchy way of doing this. thank you
