Im going to split this up into 2 parts read all of them :P Im open to improvements on this suggestion so please if you think you can make it better then please say your ideas schema will read all not just the post 
Color Slider for hull colors and hull paint:
When you buy hull its white and in order to color it you buy hull paint, say you had 1 stack of 1000 Unpainted Hull you could say 10 hull paint and then apply it to your stack then a GUI pops up with a color slider and you can customize your colors using the Red, Green and Blue Sliders.
So say you wanted to buy 100000 blank hull you needed 10000 Red Hull, 50000 Blue Hull, and 40000 Gold Hull you buy (assuming 1 Hull paint = 100 Blocks) 1000 Hull Paint and then you apply 100 Red Color to 10000 of the hull in your stack, 500 Blue into 50000 of the stack and 400 Gold into into 40000 of your stack of blank hull and BAM you now have a stack of 3 different colors, the colors could be organised in the games code by Metadata or Hexadecimal Values this will also make putting hull into blueprints easier to manage as all you need to do will be to put your hull into 1 stack on the blueprint then put the appropriate amount of hull paint in the blueprint.
Hull Buff:
Seriously, shields are the key defense in StarMade nowdays and once they are gone you can rip through the hull easily i would like to see hull at least be able to survive a few AMC volleys or 1 or 2 missile before it gives way simply because armor is armor not paper the whole point of armor is to be the second defense after the shields fail not just to make your ship look good and cover your systems.
