COLORS OF RAINBOW

IMHO:

What we call (visible) "light" is actually just a certain/narrow frequency range of electromagnetic waves!
& physical properties (frequency & phase & polarization & intensity) of electromagnetic waves (which also include radio/micro waves & infrared/ultraviolet light & x/gamma rays) do NOT actually include (any) COLOR!
The only reason we see any/all color(s) is because of certain biological structure of our eyes (which is also highly common among countless animal species of our world)!

My point is, colors of rainbow are absolutely/definitely natural/biological "design" & so nobody can really/actually claim "copyright" ownership of them!
& so, the fact that LGBTIQ people chose/use colors of rainbow as their symbol, absolutely/definitely does NOT mean, they have exclusive "copyright" ownership of them!
But, they surely can use RAINBOW FLAG (which is really a certain/special (human) design) as their exclusive symbol/flag!

Here is an example:
Think about Flag of France (which is a particular (human) design made of 3 bands of color: Red & White & Blue)!
Would it be right, if Country of France claimed exclusive copyright ownership of the colors Red & White & Blue?
Would it be right, if anybody used those 3 particular colors (on their clothing for example) to (automatically) assume/conclude,
(s)he must be French or (s)he must be trying to show support/admiration for French people?

& so, everyone can use the colors of rainbow, in any way they like, but as long as they do NOT use the RAINBOW FLAG, it should/must NOT be (automatically) assumed, they are doing it for LGBTIQ support reasons/goals!
For example, someone surely may use colors of rainbow, just for personal preference and/or fashion and/or symbols/support for diversity, optimism, idealism etc!
