This is just incoherrant.
Rejecting the existence of colour is at least consistent (if not particularly useful) in the case of radical scepticism. This would then make denying the existence of ‘weight’ a forced move.
But you then go on to say that the statement "Such an object is 10kg in weight" as having a truth value, but "this object is red" as not having a truth value.
We determine the weight of an object by using a measuring device, such as a scales. We can do the same with the colour by measuring the wavelength of the light it reflects when white light is shinned on it. I fail to see the fundamental difference here, that makes ones of these activities meaningful and the other one not so.
