could you please help me with this>>

I've read that if two colors hyphenated for singular type that means it is combination colors,if not then it has part colors like:

A1- A blue-green shirt is turquoise

A2- A blue and green shirt is one which has parts that are blue and parts green

but if we are talking about plural,then,that doesn't mean combination,,like:

B1- She has only blue and green shoes” means that all of the person’s shoes are either blue or green

B2- She has only blue-and-green shoes” means that the person’s shoe collection consists only of shoes in which each pair is blue and green.

same here:

C1- Yellow, pink, and red flowers” refers to flowers colored yellow, pink, or red,

C2- whereas “yellow-pink-and-red flowers” denotes tricolored flowers

sorry for all this but I swear I am so confused ): Which you prefer A1-2 or B1-2 OR C1-2

if you want the link of all this examples I'll post it here
