Back again to this script?

So I already got my script fixed for changing the fog color to a bluish color. Now, Im trying to do the same thing but for a different color, gray. I just don't know how to get the numbers to resemble gray. Heres the script:

function TOUCHY()
    game.Lighting.FogColor = Color3.new(0, 98/255, 1)  --It's supposed to be gray, but its making it blue.

script.Parent.Touched:connect(TOUCHY)
