As the title suggests, from last evenings set My Models Red dress and accessories seem Orange,  Her Lips and Nails remain Red.

I shoot in RAW.

What causes this and how can I correct it? 

Any tips, pointers, advice appreciated.

Many fabrics and related clothing items have "brighteners" added to the coloring.
One way to test for their presence is to use a "black" light (ultraviolet) in a darkened room, most brighteners will "glow" under ultraviolet light. Your strobes may have significant ultraviolet energy.

Selective masking and reducing yellow may help improve your current images.
Somebody probably makes an ultraviolet filter material you could try for masking your strobes. It may cut some power but should at least improve the results.

Cheers,

Best thing to do is to invest in a ColorChecker Passport and use it.  Make your own profiles for either Lightroom, DxO Photolab 2, etc.   That should get you closer overall.

You are probably shooting Adobe RGB and outputting to a sRGB source monitor or printer.  You lose colors doing that if they fall outside the colorspace.  Some colors are iridescent or have optical brighteners and will refuse to fit within a set colorspace.

I shot one of my threadracks the other day that had some reds and blues.  I know my Olympus Pen-F has a blue tendency, so I shot a ColorChecker Passport first (I was using flash too). and imported the profile into DxO Photolab 2 which gave me a better representation of the blues, and the reds look better as well.



I'm working on some scrub blue jay photo now and the file is Adobe RGB 1998 and shot that way with the camera, but some of the blue's of the bird fall outside the sRGB colorspace and will not be correct.  Some blues are okay, but it won't be an accurate representation printed so I have to live with it.  It really shows up with ColorThink Pro 3 software where you can load a 3D sRGB and then overlay the photo and see what blues I will lose.  If I could find a full Adobe RGB 1998 space printer it might get some back, but most printers are sRGB so it is what it is.

It does sound like UV fluorescence. If you shot under strobes, you need to know that they give off a lot of UV light, which can cause certain dyes and brighteners commonly used in fabrics to glow. When I bought my studio strobes, I got them with flash tubes coated to block that UV for this very reason. Check with ROSCO, who probably has a UV gel you can put over your lights. With regard to images already shot, the only thing you can do is make a selection and change the color in Photoshop, a pain, I know.

If your using Lightroom or Capture One, you should be able to make a selection and adjust colors there.

If you shoot in raw, why asking? Change to whatever color you want.

if you post the images with the problem you could better understand what to suggest as a solution.

brighteners in fabrics can cause this, they are designed to be seen by the eye and not a sensor.  I once had a guy in a dark blue blazer that photographed bright green, everyone else in the shot had the same color outfit in the capture.  The synthetic fabric combined with brighteners made his jacket go way different.
Same thing can happen with make up designed for the work environment.  Coloring in it can be meant to compensate for being under florescent light and when you put it under full spectrum you will see a strong cast, so the face and arms will be different colors.
