Ability to preview clothing based on colour in a customised way

[Sillylizzy]

Hi all,

My first post here.

I am busy designing a POD clothing store.

I will be using the "Streamline" theme from Archetype themes.

I am wanting to have a customised loading page which looks like the first image attached. The first thing users should see when the page loads is the circles with different colours. Next when a user clicks on a circle, it will provide a try on preview with that colour.

1) Is this possible within the theme - perhaps using an app from the app store? 

2) Would the circles need to be custom coded?

3) What if the user wanted to apply the orange to the top, but wanted to try blue pants on, could that be achieved.

Thank you,

Darren
