Friend wants me to correct RGB

A friend has asked me to make her NIKON colors deeper/sharper/more true. I have Canon DPP (3.10.1.0) & PSE9 9.0.3(20110328.m.11320​) for PP, used with a G12. How can I make the red, blue & green of each color better? Or can I. I have done a search but cannot find a way to make each color better. I found how to improve skin tones, make a sky more blue, or foilage greener but not how to improve each color.
Would taking a photo of a color card help? (if I can find one). I have never touched colors.
I would sincerely appreciate any suggestions. I am almost certain she shoots JPG so I will work with copies after burning the originals to CD/DVD. Oh, I have to UL her photos to my PC with a card reader.
Thank You,
Gilbert
will continue searching

What exactly does she want done to improve the colors. You have what you need in the DPP RGB Tool Palette to make colors sharper and deeper more saturated, but that doesn't make them any more true. Only your eyes will tell.
You can adjust/change the hue, brightness and contrast as well. You can adjust the tone Curves adjustment for each color channel if you want.
You and her know what should look real for the scenery, you'll just have to make adjustments until it best represents what you or her think are real.

Make a batch process that will increase contrast and saturation.

Thanks for your suggestions. She simply said the reds, blues, and greens did not look right and wants me to correct them. She has not brought them over yet but I have never tried enhancing colors. Went into DPP and all I did was make the entire photo redder or less red & etcetera. So, ran a "Search" & could not find how to isolate & enhance each color. Will try your tips and see if I/we can help. I will blame my failure on y'all

Seriously, thank you for your time and help.

You "isolate" your adjustment on the separate R, G and B color channels by simply clicking on the button for that channel in the RGB tab. Then the curve for that channel shows up and you can drag it around to taste.

Gil - Here are the basic elements of what you can do in DPP:
The simplest, fastest way is to use the automatic enhancement buttons at the top of the tool palette, Tone Curve Assist and Tone Curve Assist +. Try them to see if you like what they do. But if you want to have more control and to learn a bit about post processing , you will want to manually adjust saturation, contrast and sharpening. Saturation increases the richness and brightness of colors - push it up a bit (if these are photos of people, don't go overboard with saturation.) Next is contrast, but don't use the Contrast slider because it increases contrast in a bad way. Instead, see the illustrations below. Put drag points on the curve editor by clicking where you see them in the first screen cap and then drag the top and bottom ones to make an S-curve like in the second screen cap. Now you can experiment to get the contrast you want, the steeper the center section is the more the contrast will be. You can also move the center drag point to make the medium tones lighter (to the left) or darker (to the right). Finally, zoom the image to 100% and see if it needs more sharpening, but don't forget that the Nikon has already done some sharpening, so go easy. When you have finished adjusting them, select them all and from the File menu do a Batch Conversion.
That's lesson #1. Good luck.

I would strongly advise against doing what Tony says. If you don't know what you are doing, you can screw up the white balance pretty badly.

Well, yeah, although it's easy to undo any changes.

Aside from what I suggested, do you have a better approach to tweaking the individual colors? I was trying to respond to the question. But, I admit, I don't have a lot of experience with DPP -- I do like to play with the colors in Lightroom HSL, though!

Well no, 'cause you can't in DPP. But I think that what GB's GF meant by "fix the RGB" is to improve all the image colors, not just the primaries, and there are two tools for that; Hue which can correct (maybe) or cause a color cast and Saturation.
