What parts would be needed for timer with light panel indicator

I want to put together a little project that would be a timer with a light indicator panel (much like a mini LCD screen)
It will have 4 buttons.
Button 1 would turn the light panel green, button 2, yellow, button 3, red, button 4 would flash the light panel green, yellow, red.
What hardware would be needed for this, outside of an arduino nano and momentary push buttons? Not sure what light or screen would be called that would be used.
@mrhutchinsonmn what type of light panel are you thinking of?
Something like https://www.ikea.com/us/en/catalog/products/20303063/ (60x60cm)?
Or something smaller like https://www.aliexpress.com/item/32959082165.html ?
Or something super easy like a single RGB diode (or one red, one green and one yellow) behind a piece of white plastic to act as a diffuser?
I think what I would like is a Light Panel that would be about 7 or 8 cm square. I'm not sure if I would get the clean look that I want with the LEDs you mentioned but maybe you could point me in the right direction so I could consider those also.
@mrhutchinsonmn just put any thin sheet of white plastic on top of a led
@mrhutchinsonmn I would probably use a diffuser instead of lens but yes that would work very well
Here is my first prototype of a working solution for a timing light: ( neopixal timing light):https://youtu.be/b3TDGKUS05I
Thank you for direction @mfalkvidd !
Great video @mrhutchinsonmn, thanks for sharing!
I really like the real-world use case.
For the wireless part, you might be able to reuse parts of my code for a pomodoro timer. https://youtu.be/sLEbq_pfry0
My code does not support remote control (it only views status remotely) but it would be easy to add en endpoint, for example
I like that! before your reply, I found something else that would work. I like it because a nano could power the neopxial and rf receiver, reducing complexity
This is what it looks like with a diffuser
@mrhutchinsonmn sorry, I am not able to open that link. It just goes to Ali’s front page
