Should it have an initial and final value? I've done it as the example on #157 but it might need those values...

588 - Polygon color, classed (color steps)

@Lady-Aga nice! can we see this with 7 class breaks? Typically, that will be the maximum (although with VL, ppl can choose as many breaks as they want). For these classed legends, I'd say the minimum would be 2 (more likely 3) and the maximum will be 7. According to CARTOColor schemes, we have sequential and diverging color schemes for: 2,3,4,5,6 and 7 classes.

I should mention that [diverging color schemes]( will usually be an odd number 3,5,7...)

From our CARTOColors page: "Diverging schemes Highlight values above and below an interesting mid-point in quantitative data with these schemes. The middle color is assigned to the critical value with two sequential type palettes at either end assigned to values above or below."
