Change the Red Color on Widget

[radiodj105]

Hi there.
This application is perfect. However, I think that the red color on the widget, is not very visible in most devices. I do own an HTC Desire Z and a Huawei tablet. In both devices, the red color looks not good. I think that the yellow, orange or green light should be better.
Unfortunately, I can't have the option to change it, myself.
