How do i do this? % of color?

[IcePack]

"Fill the Background Layer with 55% gray. Get the Type Tool and type "A". Set font to a favorite of yours, i’m gonna use Bauhaus 93 font and gonna set font size to 200 pt. Set Text Color to 40% gray. Rename the layer as "Text", this will be important later."

I understood how to do it 5% color,but can't understand what the author of this tutorial meant by "set text color to 40% gray".I mean how do i make it 40% or something?

Here is the tutorial.

In RGB, pure white is 255,255,255. and pure black is 0,0,0. Anything in between those values is a shade of grey. So 40% grey would be 40% off of pure white, 40% of 255 = 102

255-102=153 therefore set RGB to 153 for approx 40% grey

255-140=115 = 55% grey

After you set the color, look at the color picker and notice the % value in B, under HSB.
