Amber/Green composite TV Out

Using Arduino Displays
1

Hello,

I undertook a small project to create a computer that measures the engine temperature, RPM, and fuel levels of a retro car equipped only with analog gauges. I achieved this using an Arduino and then displayed the output using the TV-out library on a small 7" TFT color display that supports both PAL and NTSC standards. The rationale behind using composite is the simplicity of keeping the ArduinoUno in the engine bay, connected by a single coaxial cable to the cabin.

The system functions well; however, aesthetically, I would like to have a monochromatic display, preferably in amber or green, to replicate the appearance of old retro displays.

What would be the easiest way to achieve, for example, a green or amber display using the TV Out library? I considered an external solution, such as employing a VGA to composite converter and then transmitting only the green signal, but this appears to be overly complex. Is there a simpler method to generate a constant color output, regardless of whether it is NTSC or PAL?

A green film / filter, cut to size ?

Yes, I have considered it (I forgot to write it in the previous post); however, the problem is that I also intended to use the same screen for the reverse camera (it has two composite inputs).
