Factory Color Choice Sequences

[DW69K0]

OK, everyone will laugh at the simplicity of this question,  but could Honda have decided the color of the Sancast by a simple even or odd frame or engine number, or some combination there in?
I have an abundance of candy blue green bikes and only one candy ruby red Sandcast, when I compare my frame vin number all the frames with odd numbers are candy blue green and the even number one is candy ruby red.
I know this theory will not hold for long, so did anyone ever figure out how the factory decided the paint color, I know it was not random (guessing), so what are the theories on how body set colors were decided?
Best,

fwiw........  4363 had red h.l. ears and h.l. bucket.  ain't got pics

1865 underside of tank, inside of side covers and h.l ears, b-g.  didn't bother to take pics

2157 definitely had b-g original parts on it, tank underside, h.l. ears.  pics enclosed

232 had all gold ko parts on it, so.........  pics enclosed

personally, i believe there might maybe perhaps possibly have been more b-g bikes than red.  back in the day, i remember seeing more b-g than red bikes.

There are no silly theory, because everything is possible ...
Personally, for 1969 and the beginning of 1970 .. I have never seen a blue Sandcast Paris and surrounding...   Only red motorcycles... and yet, I was riding a lot in 69 and 70...

The b-g color had a short life.  Only about 10 months.

I think theory of odd and even numbers, while original sandcast 889 and 1095 were red and 446 was b-g.
I agree with Steve, I think also there were more b-g bikes.
Question is, how these bikes (colours) were produced on assambly line.
