White on green is one of the hardest color pairings to read due to how cone cells are distributed in the retina (this image isn't completely representative, in the fovea green gets even higher as a proportion): https://en.wikipedia.org/wiki/Photoreceptor_cell#/media/File:ConeMosaics.jpg https://en.wikipedia.org/wiki/Photoreceptor_cell#/media/File... That's RGB lit up contrasted with just G lit up. One of the only worse pairings would be white on yellow, which would be RGB vs RG lit up, with the only distinguishing signal coming through blue, which we have the lowest resolution of. White on blue is RGB vs B, all the visual difference in RG which we have the highest resolution of. This is why you generally want different color schemes for light vs dark terminals, if the color saturation is high (saturated blue text on black is bad, saturated blue text on white is fine and vice versa for green and yellow).
