I'm plotting a 2D contour plot using contourf(X, Y, Z). How can I create a custom colormap, where certain color would be bound to a curtain value? For example:
100 - [1 0 0]
200 - [1 0.5 0]
1000 - [1 1 0]
It would be also nice to make all values below 100, for example, [0.5 0 0] and all values above 1000 - [1 1 0.5].
Please, do not suggest colormap editor. If this task is impossible for colormap, suggest me another function for 2D plots (maybe, plot it dot by dot)

To confirm: if the input value were 100*(1+eps) then the output should be transparent because the value would not be any of the ones you listed?
