While the skulls were drawn with an erasable pen, also could mean the 'black label' may be erased later. So, the trick for Gosho (like professor Agasa) may be to first introduce three suspects as possible candidates for Rum or BO agents, while at a later date revealing them to be either undercover agents or on the side of 'red' ('not black')
What we call black tea in English, the Japanese call it red tea (literally), so you may be overthinking this one aspect.
Same goes with Chinese (红茶). It's called that based on the tea's coloration when brewed, while English is referring to the tea leaves while dry.
While I wouldn't put it past Gosho to play with it, since red and black is a recurring motif, there is a point where one could argue it could go either way (going toward red, implying good, or going toward black, implying bad) without outside information.
