@Lee-White - what a great question "what's the MAIN color cast of this image?" that you've suggested to help keep things under control. Have attached the original image & the updated image - not intended for you to critique, just to show there does seem to be an improvement on overall color harmony from my view after trying the methods you advised – thank you! Stress levels lower too! And after sampling & stealing some other artists’ colors (this is fun to do too) - realized that my image has fundamental issues in the drawing & value areas that pretty colors can’t hide/fix.
Yes! – have been enjoying seeing your low contrast paintings – thought them intriguing, like someone whispering instead of shouting
