are you referring to colour if so. you can change it in the skin folder. look for the configuration settings. it is usually labelled as 'skin' sadly I can't show any footage of what i'm talking about but you should be able to find it easily look for the catch the beat section which should look like this
[CatchTheBeat]
HyperDash: 225,255,255,255
HyperDashAfterImage: 255,0,0,255
HyperDashFruit: 255,0,0,225
you can change and adjust the colour by changing the the numbers. not sure what are any of the color codes but hopefully helps you a little
