The back ground color is too dark, is it possible to make it lighter ?

How can I change the lowest value's color with the commandline instead of clicking 'edit' ?

You could use colormap() to activate a different set of colors.

For example:

cmap = colormap();   %fetch current one
cmap(1:20,:) = [];   %get rid of the 20 darkest shades
colormap(cmap);      %activate the revised colormap
