The short answer is: make some tests.
If you have a camera with manual mode, specifically you need to turn off auto white balance settings.
Take some pictures of some white color objects, like a sheet of paper. This need not be overexposed.
Then you can use any photo editing software and compare the rgb values, and make some adjustments.
If you want more professional results you might need to buy a graycard that will cost you like 8-10 dollars, taking a photo in a raw format, measuring the light with some lightmeter, and using a raw image processor, like Lightroom. But there are some free programs that can help you here like:

Use the white balance tool, (the one that looks like an eyedroper) and again, compare the results between your light sources.
But you probably don't need to have a perfect balance there. You can always take a more artistic approach.
