I am sampling from a texture and if the color is somehow gray [vec3(.8), vec3(.9)] and an uniform is 1 I need to substitute that color with another one

I am not a glsl veteran but I am pretty sure there is a more elegant and compact (without mentioning faster) way than this:

vec3 textureColor = texture(texture0, oUV);

if(settings.w == 1 && textureColor.r > .8 && textureColor.r < .9
                    && textureColor.g > .8 && textureColor.g < .9
                    && textureColor.b > .8 && textureColor.b < .9)

I'm currently making a cube style game. With chunks being drawn with VBOs. I'd like to know if there is a way to create an overlay texture on top of the existing texture without the need to rebuild the VBO.
