Shop Brands/Variants/Options

Hi!

I'm considering to use perch a for a new project where we will need to sell products online, but I'm wondering if the perch by default can do a specific thing:

In some cases, we will have products that share similar characteristics, for instance, we would like to have 3 distinct products that have a blue dot. If for any reason, we want to change that blue dot to green, we should be able to update them all at the same time, instead of going one by one.

I'm aware of Brands/variants/options, but until now I only used options and I don't think I understood exactly what I can achieve with brands. So sorry if I'm making a obvious question :S

Thank you for your time
