S7 Stock E-mail program headings/title colors

[BJB1]

Moved from the S5 to S7 and have always used the stock e-mail client as one of my e-mails sources is an exchange server (not 365).
I really did search for this answer, but most answers were old or were talking about the background.

Anyway, my issue is the colors that the app uses (I guess randomly by account?) that it uses for the top headings (inbox, e-mail name, search, more, and the icons). They are cartoonish. One of my accounts is orange, one is RED. I mean every time I read that account I think I did something wrong or the phone is giving me a warning message!

Is there any non-root way to change the color? I found the way to change the calendar color with the little icon next to the account...so no app needed like with the S5. But these e-mail colors....hopefully I am missing a setting somewhere or there is a developer that came to the rescue.

Other than that, really like the S7 Edge so far.

Thanks,

BJB1

There is the negative option in settings.. but it will make everything else looks like junk. I like the stock email app but I wish I could change the background also. my eyes are bad enough.
