Hi,
Thank you for your message.
Yeah, this is surely possible. It however depends how you would like to approach this. You could create dependent fields which would mean that you would hide/show certain fields based on their condition. So if e.g. if you had a drop down form control and selected size M you would show colors another field with given available colors.
This has a disadvantage of having multiple fields -> each for any combination of colors which might not be good for you.
Another option is a little more advanced and that is to create your own form control and along with dependancy you would load appropriate colors.
Some reference to dependancy fields is here ->

Kind regards,
