Hey Orestis,

Your sketch of the OC is a very good one, particularly as it includes the electric blue of Tau Canis Majoris. Colour is one aspect that is often missing from astro sketches. Sometimes, not because the object doesn't seem to have colour, but we either miss the colourful stars, or we hesitate in using grey or even a pale blue in the item, an white alone doesn't quite do it on its own.

Particularly with galaxies, GC's and nebulae. Grey can soften the otherwise harsh white, and the blue gives an element that white just doesn't have. Our eyes perception of low light isn't strictly 'black and white with shades of grey'. It's a little more complex.
