Three main colors for my ships! A white/light grey base, usually. Accents being a pale blue and varying reds. The pale blue is for accents and is the second-most common color on the ship, while the red is used to highlight weapons. Yellows sometimes show up, as well, since it's the standard warning color.
Overall the design was meant to be decently generic and not stick out too much, while still being aesthetically pleasing and fitting. White/light grey to give off a ''blank slate'' vibe. The pale blue to make it feel a bit softer overall, and not as harsh. And the red for the weapons because it sticks out a bit, but not too much. Yellows are, well, for caution and the like. The usual stuff.
The colors sometimes change depending on where on the ship they are. Underbelly and such tend to be a darker grey, for example. A point sticking out would be either black or white. Things like that.
