Something one anon already struggled, white balance.
Or easier: how to make a picture look less blue or red straight from the camera.
This is actually pretty simple to understand.
Most cameras have a WB button or setting in the menu, and often they have already saved some presets for daylight, flash, cloudy or fluorescent light and AWB, auto mode.
Color temperature of light is in K (Kelvin).
The lower the number the warmer the light, the higher the number the colder is the light.
The light from a candle for example is 1000K.
You might see this when buying bulbs for your lamps, lower K makes for a warm and cozy light while the ones with more K tend to be colder.
Now, when you change the settings on your camera you will see it the opposite way.
Lowering the numbers will make a colder picture, raising them will make a warmer one.
Your goal is always to reach a "natural daylight" look.
So when you are taking pictures in the middle of the night with some shitty desk lamp and everything is red that means you need to lower the K number.
Alternitavely you can use one of the available presets, in case of warm lamp light it's usually a "bulb" icon.
Again, test it.
Put up a set up with some lamps and then look how you change the WB setting in your camera.
If you can't change it you definitely should invest in some daylight lamps, their light is already a pretty neutral temperature and it helps greatly in taking pictures.
This is true in general.
