It's the CX201G, there's also the CX201R.
G for green, R for red. They are foreign models, like the UK.
If it doesn't have the G/R at the end of the model number, then it WILL be Blue. The seller might be showing a pic of the G/R model, but ask for the model number if you so choose to purchase it.
To my knowledge they have not released the G/R models to the US yet, that's not to say that they haven't though.
