This red could easily compete for my spot as the reference color. You will not be disappointed if you are a fan of AIO Robotics filaments. This color slightly reacts to UV light.

AIO Robotics has to be one of the most consistent brands I have ever used. Another great thing about AIO is the spools are sold in half kilogram sizes. For a color which you may not need to use a lot, these smaller rolls will save you money. They also store easier and each come in a resealable bag. AIO Robotics often has colors out of stock. Watch out, AIO had older 1KG sizes on Amazon. They reportedly don't have the same quality. Perhaps due to age.
