Capitalizing adjectives that define colors

[Seagull]

Since we are in theme of discussing instructors grades influenced by their own bias, I noticed a trend that I wasn't aware of and thought it was a typo until recently the ny times made note of why they are doing it. 

Some adjectives defining colors are capitalized, while others aren't.
And it has become more and more common.

But the question is since lots of auto correction programs like ms word and turnitin are not updated on this trend, those who capitalize adjectives are going to see it as an error.
And those students who refuse to capitalize one color over another because they believe in equality will have their grade affected by it.

Is all this a type of orwellian newspeak?

I guess we all have to do our best, ...I mean our plusgood.

Not wanting to start a big debate but I feel this will become a problem when writing papers once the change reaches academia.
