Hello ,
I'm trying to change the colormap on my heatmap, I'm using right now the '"money" color but I'm want to be blue one, I tried many options without any luck. Any help will be appreciate.
Thanks.

Here is a helpful resource for this question. You can make and save any colormap you want throught the colormap editor:

Change the Colormap property of the heatmap, either when you construct the heatmap:
h = heatmap(magic(5), 'Colormap', copper);
or afterwards.
h.Colormap = flag;
If none of the predefined colormaps are suitable for your application you can build your own as an M-by-3 matrix, either manually or using the colormapeditor as per Jessica Lovering's comment.
h.Colormap = repmat(linspace(0, 1, 25).', 1, 3);

You can also use the colormap function:
figure
heatmap(magic(5))
colormap(parula)
or
figure
h = heatmap(magic(5))
colormap(h, parula)

There's also a new colormap named sky introduced in release R2023a that may be of interest if you want a colormap from white or very light blue through dark blue.
heatmap(magic(4))
colormap(sky)
