Red bias on G2 pics

Has anyone noticed a red bias on pictures taken with the G2? I've noticed a red bias on my pictures, but didn't really pay attention until I took this picture of flowers recently and got a very noticeable red bias.

First photo is untouched, taken RAW with 550EX, 21mm, 1/100, f4.5 auto WB.

2nd photo has correct color as I remember it (after red levels adjustment in photoshop)

3rd photo is with WB set to flash before conversion.

Is there any way that I can configure the G2 or use photoshop to remove the color bias automatically? Am I stuck with adjusting red channel for every single photo? I’ve read about G2 color profile on some posts here, but I think it only works on linear files. I tried assigning G2 profile to the file but ended up with very washed out colors.

Comments and suggestions very much appreciated…

I have the same problem with the skin color under indoor light. I adjust the white balance setting in the camera manually, not setting it to AUTO, still. Does anybody knows how to fix the problem.
I'm shooting in the JPEG mode. Will the RAW mode help?

Thanks in advance.
