One can use texture:SetVertexColor instead in this case. See the example below for the way Blizzard handles this.

New page

Sets a texture to be desaturated, to make it greyscale.

shaderSupported = texture:SetDesaturated(desaturation);

----
;''Arguments''

; desaturation
nil = normal colors<br>
1 = desaturate (greyscale)

----
;''Returns''

; shaderSupported
So far haven't gotten a return other than 1. Likely nil or false if desaturation isn't supported due to the user's graphic capabilities. (see below)

----
There is a wrapper function in UIParent.lua that appears to darken the texture if shaderSupported returns false:

-- Wrapper for the desaturation function
function SetDesaturation(texture, desaturation)
local shaderSupported = texture:SetDesaturated(desaturation);
if ( not shaderSupported ) then
if ( desaturation ) then
texture:SetVertexColor(0.5, 0.5, 0.5);
else
texture:SetVertexColor(1.0, 1.0, 1.0);
end

end
end
