how do set the correct colour in your image?

I have been reviewing my images and have found it hard to work out what the correct colour should be for the objects.

Any suggestions about how to achieve an accurate colour for your images?

The most accurate way is G2V star calibration. Here is an excellent tutorial by Don Goldman:

Greg,
One can take G2V calibrations each night to be very accurate. Or you could also use past data. The key is to make sure you take the image with the star unsaturated (i.e. usually very short). I use past G2V data regularly in calibrating colors on processing.

You can separate your colors on the DSLR data and do the same thing.

Also when shooting any object below 45 degrees you may want to consider an Atmospheric Extinction correction as well in your processing.

Here is what I do:
