How can I match my supplier's website color combinations on Shopify?

How do I get my shopify replicate my suppliers website. they have multiple colour compbinations eg
white mattress black base
If I try to set up 2 separate colour schemes my shopify does this
black/cream

I want my client firstly to select the mattress as white
and the base as black

Sorry, but can this be done. Is there a work around for multiple colours combined?

Would metafields help please? I am eager to start selling these items but can’t until I have all the variants set up

Sorry this is another question I need to know if it can be done with shopify. I will lose this client soon.

I need to set up on my own shop the four parameters that is
Colour of mattress

Colour of base

So want I would like is the customer to select the colour of the mattress ----say cream

and then select the colour of the base -----say grey

but shopify will not do this.

Again is there an app or anything I can use

thank you

Yes exactly I was facing some issue in my shop page as you can seehere some of the points are same with your problems.
