Last night I woke to go to the bathroom and used my phones light so that I wouldn’t wake my partner.
The light from my phone shone through a green glass bottle and lit the wall up green.
Are light particles uncolored and just affected by the colored glass or do they have properties that are changed?

Light particles do indeed have a color.
It’s just that “white” light is when a mix of all the various colors are hitting our eye at the same time, in about equal amounts. Our eye’s specifically pick up, red, green, and blue light and any other color is just a mix of those. (this is a bit of an over simplification, but broadly correct I can elaborate further if you want)
Any time you see a different color than white it’s because the light is actually lacking particles of a particular color. In your example, the white light went through the green glass. And it then absorbed all the non-green light (this slightly heats up the glass, btw. Leaving only the green light behind.
