C≔ColorDivergeBKY 21
C≔⟨RGB : 0.153 0.498 0.827⟩
You can programmatically access the colors using ColorTools commands.
P≔GetPaletteDivergeBKY:

SwatchesP
DivergeBKY is best used to construct a sequential gradients which diverge from a central value.
ColorTools:-SwatchesP,mode=gradient
The Blend command can be used to create a function to color arbitrary ranges. It can take the name of a palette to generate a colormap.
ColorMap≔ColorTools:-BlendDivergeBKY:
ColorMap0.35
⟨RGB : 0.171 0.237 0.342⟩
And is particularly good when used to color surfaces. The colorscheme option of plots can take the names of palettes to generate gradients.
