Because Monty said that Dust is color coded, meaning one color = one type. It's just that the way that Dust use has been presented to us so far hasn't been very clear or consistent.

It's possible that Neon's nunchucks filter the glow from the Dust inside to make it a much lighter shade, for example. The concept art shows it glowing pink, but there is no pink Dust. However, it's possible that her nunchucks make red Dust look pink. But since that's speculation, we can't really put that on an article.

The only color that we know for absolute certainty is green because we were told directly that green is air/wind Dust.
