Color Swatch King: Variants

This should be a standard function of Shopify, but in the meantime this app delivers everything we needed. We are using this with BoostCoommerce Filter & Search app, and Variant Image Optimiser (also by StarApps). The combination has allowed us to have complete control over our multicoloured product options across the site. I would also like to mention Utpal who was amazingly helpful and quick. We applied some customisation that looks awesome. Highly recommended.
