How do I make a paint mod darker?

[user1679]

I have old paint mods by freeq's and axeface and wanted to darken some of them. There are yellow, green and orange that are all bright and glossy and I'd like to make them more of a dark matte color. I used Photoshop to get the proper saturation and RGB values but it still doesn't look right on my ship.

Here are the values for a dark green but it looks like bright lime in game:

hue="54" brightness="-1.4" saturation="-1" metal="-1" smooth="0.36" dirt="0.18" extradirt="-0.01" strength="0.8" scale="1" sharpness="100" invert="0" red="114" green="157" blue="34" alpha="255"

I removed the value for pattern to avoid line wrap but the path points to a texture that is solid white. I tried removing it but the ship just turned grey as if it had no texture at all. So I'm trying to get my ship to look dark green (eg: "forest green") instead of like a giant piece of space fruit. Would appreciate any pointers.
