Annotated heatmaps: font colour blends with the colour of the square.

See original GitHub issue

When using the default color scheme, the font color contrasts normally with the fill of the each heatmap square. But if you try other standard color schemes with reversescale=True, when values are close to zero, the colors will merge. I think this is the wrong default behavior.

Hello, @jonmmease! Bug can be reproduced when using zmin and zmax arguments. Plotly 4.5.0.

from random import triangular
import plotly.figure_factory as ff

z = [[round(triangular(0.01, 0.1), 3) for j in range(10)] for i in range(10)]
ff.create_annotated_heatmap(z, colorscale='greens').show()
ff.create_annotated_heatmap(z, colorscale='greens', zmin=0, zmax=1).show()

Without zmin and zmax: without_zmin_zmax

With zmin=0 and zmax=1: with_zmin_zmax
