Image on color swatch doesn't show on product page

[Emmalu]

Hello! I am trying to add image to my variant options, one of them is "floral" pattern and I added image in the color entry. I also added them in the color swatch but it's still now showing. 
I am using Nordic theme. The link to the certain product is here:

(passcode: nowgep)

I am attaching what I have done so far

Can anyone help me here please?

I did not want to install app because it will ruin the style.

Thank you very much!

You should choose a color as a basic way. If you want to add an image in your metafield it can be diffucult for somebody who does not know software. If you want I can take care of it for a certain.
