metal flake

Re: metal flake

Our new standard deduction guideline puts the issue of metal flake size + density into the category of paint Color. We changed our judging rules on exterior paint a few years back to intentionally divorce the Color aspect from the paint's basic composition and application.

So, it appeared to me, that this was a giant step backwards for NCRS. But we 'salute the uniform' and go forward.

My question is: does a colorimeter actually see a significant difference in actual color temperature based on minor differences in metal flake composition (aluminum vs. lead + flake particle size/shape)? We already had a standard deduction guideline for 'hue'...

The reason for asking is it seems to me like the reflectivity aspect of the paint (sparkle and gloss factor) should NOT be associated with the Color axis of paint and should be a paint composition issue falling under the Paint axis of our judging.

So, if a colorimeter (which we don't use on the judging field) doesn't record a significant change in actual color temperature based on minor deviations in metal flake composition, aren't be better served by putting that issue in the Paint vs. Color line item of Flight Judging?

My head hurts!
