Quote - What you did is fine, but it basically converted some of the shader back to old style, without gamma correction.
So really what you did was raise the true gamma-corrected Diffuse_Value by about .15, which is what I was going to do anyway. :)

Oops; well it worked for that texture. Tried the shader with the Grace texture for V4, this time with your indoor03 light set. I changed the simple node color to a barely blue/green tint to tone down some of the red.
