I'm a longtime WM/H player, and in that game, you can paint your armies whatever color you like and your opponent will still know what/who they are. But in 40K, it seems like Space Marine chapters are decided by color scheme.
To be honest, the vast majority of
40k armies are like this. It's just that Marines all wear very similar power armour so it can get a bit confusing. However, they have other signifier as well. For example, Dark Angels aren't just signified by 'green'. They also have robes, sword Icons, differently coloured terminators, etc. Space Wolves wear pelts, look feral, have animals all over them, etc.
You can, of course, paint your models however you like - the general rule to avoid annoying anyone is 'make it obvious to your opponent what you're playing'. This can be easily done using all these modelling signifiers.
For example, if you want to field regular, normal Marines, and paint them green, then great. Do it. But if you paint them green, dress them in robes, give them Dark Angels symbols etc, then you might confuse your opponent into thinking they were Dark Angels.
If you want to play Dark Angels, but you want to be a blue-painted successor chapter, well that's fine too. But you might want to put some robes or
DA symbols or something on them so that you don't make your opponent think they're Ultramarines.
You can do whatever you want, and the fluff is very open ended for that reason, but it's always good to make sure that your models look like what they're meant to represent...
