Taken from a two-part blog post I've written a long time ago, in an old platform called Blog(dot)com before it died.
When viewing through competitive copying glasses, the two colors picked here symbolize two sides, sometimes two equal sides & sometimes one is higher than the other and we gotta side with the lower one to one-up the higher one. Starting with the basic red vs blue which is in a lot of fandoms, and pink vs (light) blue too to a certain extent.
Believe it or not, this video was recorded LAST YEAR, when I still used that Scarlett shampoo & conditioner pair. That's how long it took me to finally get motivation to make the soundtrack cuz I need at least a new background music to differentiate from Rest Assured. It was fun dressing in half&half & wearing half&half makeup though.
