I want to build this speech timing light so I don't have to buy this official light
It sounds to me like you're planning to manually switch the lights. If you want to build that, maybe copy this design: https://www.amazon.com/Toastmasters-Timing-Light-Timer-Included/dp/B00L44M9FK ... no logic is involved and no Arduino needs to be.
But... this is a perfect Arduino project.
I think I would use an Adafruit Neopixel Ring 12 (it has 12 LEDs that are multicolored). You can use your programming to let it display dim white for all but the last two minutes, change it to green for qualified, yellow during the warning minute, and then red.
You can program it with long button presses

If color blindness was a concern, we can do something with patterns (gentle double blink pulse on yellow)
Hardware
If you want to do your own timing and light switching, you can change the usage case in your programming
Nothing automatic will happen. You don't really need an Arduino for that.
