"This reinforces the 5.1σ (4.7σ) rejection of the 2+ (2− ) hypotheses previously reported by the Belle collaboration, and confirms the 3.4σ (3.7σ) indications from Belle that 1+ is favored over 0− (1− )."

I thought the new particles were cool because they don't follow the color charge analogy, whereas mesons do follow the analogy?
There are some abstract algebraic properties of the particles and these properties produce the color rules.
With 4 quarks the only possibility is a mix of 2 quarks (with colors) and 2 antiquarks (with anticolors). For example red+antired+blue+antiblue.
