FUTURE GAIN COLOR: Turquoise to White Gradient. Hear me out. What if all the bottles were colored according to how much scent they would leave behind after a wash. The white could be a "scent free" option for people with sensitive skin, and dark turquoise could be a pretty intense scent (for if you're washing something stinky like gym socks haha). You could pick the scent level according to your liking!
