Do you have ideas on how to get gray wall renderings to represent the true color it would have? I'm trying to see whether I'd like to have the lighter gray on my walls or the darker one, but the darker shades of gray get rendered way too light (if you ask me [:D] ).

Here are the walls pre-rendered:
Color L500 (RGB #A8AFB5):

and color S500 (RGB #757B81):


and their corresponding renderings:
L500:

S500:
