COLOURWAYS
UV REACTIVE
Some Colourways are also UV reactive, for them to glow you will need an Ultra Violet lamp.
Many club venues and festivals will have these already however if you want to purchase your own you can view the one I personally use here.
Generally, pastel shades tend to glow the most under UV light and also have the smoothest gradient, darker shades wont react as much. UV colour dye options include Red, Pink , Purple, Orange, Yellow, Green, Mint, Blue + Optic white which shows up as UV Blue.
