Sanjib, it would help if you can explain exactly what it is that you are not happy about the exposure. By "exposure" I am referring specifically to the brightness or darkness of the foreground subject (buckets) and the background.
But in the meantime ..................
No, not if you are happy with the result.
But when shooting indoor shots with low light you may be forced to use a low shutter speed that is going to cause camera shake problems or the result will be affected by subject movement. These can possibly be overcome by increasing ISO but that is going to increase the noise.
There's a big difference between shooting a static subject from a tripod than shooting a fidgety child hand held in low light
Assuming you are shooting
without flash, if you use Aperture priority, you need to know exactly what your Speed is doing. You could use Auto ISO and set a 'Minimum' Speed.
Personally, I would ignore colour at present until you become more practised and confident with your exposure procedure.
