pink
Look to your lighting, or consider trying several different colors of background.
Ordinary lighting in homes is usually very yellow, which can make regular photos look rather mustardy. However, there are pinkish bulbs out there (marketed for their \"warm\" light) that could be turning your stuff pink. You might need another light source with a \"daylight\" bulb, which is a specialty item at the hardware store.
Alternatively, you might try putting another color of background up behind your mini. It could be the color balance of your minis is making the camera \'compensate\' the wrong way. Try taking a photo (in the same conditions) of several shirts of different colors. Each shirt should be a different photo. See if your camera skews the colors one way or another for each shirt. Then try taking photos of two contrasting shirts together and see if that helps the color balance. You may find that if you\'re taking photos of several green orcs together, you need a red background behind them to balance so the camera doesn\'t compensate.
I usually find I have to take pictures with several different backgrounds and different lighting conditions to get a picture I like. Each mini has a different set of colors, so it will look better in different conditions.
If I put a light-colored mini on a white background, my camera adjusts the exposure (on auto mode) until everything is medium grey. This makes my pale unicorn look horrible. On the other hand, if I put the same mini on a dark background, I may lose some details in the highlighting and shadowing because of the high contrast. You have to experiment with different backgrounds to see what works with each one.
With experience, you\'ll know better from the start which backgrounds and lighting will look better with your mini, and you won\'t have to take so many photos to get the good one.
If lighting is the problem, you can try other bulbs, or get three or four different kinds of lights and try each one in sequence and in combinations to see what works out the best. Or you can take your stuff outside and photo it in the daylight. Just be careful of stark shadows, because they\'ll obliterate your careful shading.
