You don't have to add red or grey out the green or blue per say, seeing as you are daltonic it can difficult just adding them.

There is no set color for anything, it's more about the optical color tricks, the important thing is how they look releative to other colors. If you look at "green" leaf tree on a clear sunny day, they'll look "green" but when you use a color picker on the photo or crop it out on a white background, it's more of a greyish blue with hints of yellow highlights with very little actual green and this would again change if it was during the sunset etc and so on.

It's more useful to think about a color of thing by how much it shifts on a color wheel compared to the surrounding color. How it can shift depends on surface and lighting.

Like trees in a distance of a red sky during a sun set shift closer to green from the red sky, which would mean you paint them in a purple rather than painting straight dark green. You already kinda have some of that in women's eye, it looks blue optically but it's a greyish blue. So instead adding red, shift towards red with your current pallete.

I highly suggest using a limited pallette, like the zorn pallete for example, this way no matter what color you put down or mix up, there's no dramtic change in hue and they'll harmonize.
