"On white" is the contrast ratio against a white page. "As text" is whether that ratio passes WCAG AA for normal text, which needs 4.5:1; large text needs only 3:1.
Where the scale turns over
green-700 is the lightest shade that reaches 4.5:1 against white, so it is the first one usable for body text on a white page. It is also where a background of this hue stops taking black text and starts needing white — the two thresholds are 4.5:1 and 4.58:1, and on this scale they fall on the same step.
Using green in Tailwind

<p class="text-green-700">The text class above is the lightest green that still passes AA on a white background.
