Can different products use the same svg (from designs) but in predefined colours?

 Hello,

we use several svg Graphics as Designs for our customizable Products. We offer different products and the colour choice is very small. Lets say

Product A can only have black colour graphics and

Product B can only have grey graphics.

The graphics are the same and are uploaded as svg. Do i really need two design libraries (one in black and one in grey) or can i use the same library and change the colour of the svg when the user selects it?

thank you so much,

tm
