Customization rpm bar round

Hello,
The RPM indicator allows for customization of the background image and color segments in the linear (bar) version, but not in the circular version. For the linear version, you simply select a 1-pixel image containing the desired colors. With a circular indicator, however, we can only set a specific RPM threshold (redline start) at which the display switches to the redline color. This limits us to a single operating color followed by an alarm color. I would like to have multiple color ranges, but unfortunately, that doesn’t seem possible. For example: red below 1000 RPM, green up to 4500, yellow between 4500 and 5500, and red above that. Do you have a solution?
I tried layering multiple indicators with different ranges, but it didn’t work because there is no transparency, meaning only the top layer is displayed.
Thanks.

Since then I've figured it out by playing around with the on/off switch
