DOUBLE LEVEL ATTRIBUTE

Hello, in my e-commerce, i have a customizable t-shirt with 2 lines on it. The user, have to choose the base color of the t-shirt, the color of the first line and the color of the second line; BUT colors are segmented in: winter, autumn, and summer.
So, the base attributes are:
– Base t-shirt color
– first line color
– second line color

Now, the problem is: i wanna that all of those 3 attributes, could be segmented in: winter, autumn, and summer, and the color terms inside those 3. It’s like double level attribute, you know how to do that?

i hope i explain myself good
