Can some colours be processed faster/more accurately than others?
The answer is yes and yes. Firstly, motion cannot be processed at equiluminance. In other words if you have clubs that are equally as bright as their background you will not be able to see them move even though they are clearly visible because of a different color. It's a remarkable effect (demo link below), as you become in effect motion-blind. Obviously you notice after a while that things moved, but you don't see them move smoothly as you are used to. This is similar to what people with akinetopsia experience (had lesions to brain areas involved in motion processing). So have clubs that have clear luminance contrast to the background (very dark, or very bright).

Then there are known difference in processing latencies for different colors. More specifically yellow is processed faster than blue. And black is processed faster than white (if you consider them colors). These effect are massive, a few hundreds msec in some cases which is very long. There is also a known relationship between stimulus intensity (here color contrast) and response time, called Piéron's law. However that effect saturates at fairly low contrast so as long as you can see the clubs clearly it's unlikely there will be a difference in response time for more contrasted colors.

Finally there are discrimination differences for colors. For example yellow and orange are more easily discriminable than blue. But that's only true if you have to perceive a low contrast color difference (a yellow club on a yellow background). Here again as long as you see your clubs very clearly, it's unlikely the specific color of the clubs will make a difference.

So overall I would recommend to use clubs as contrasted as possible to the background (which is common sense). Then prefers darks to lights colors, and prefers yellows to blues. The ideal color is brown, which is in facts a dark yellow.
