scatterm with scatter marker pink to red color based on values

Hello,

Based on another post I have been able to find how create a scatter map with marker size and color based on the data value, but I would like to change the colors to range from light pink to dark red so lump the lower values into pink medium into red and large values into dark red. I have not been able to figure out how to do this. I would appreciate any help, thank you.

This is what I have so far where the colors range from blue to red.

scatterm(lat20,lon20,z20*10,z20,'filled')

Update: I tried the following, but I am getting an error message about scatterm format being incorrect.

C=[1;0.713725;0.756863;1;0;0;0.545098;0;0]; 
scatterm(lat20,lon20,z20*10,C,'filled');

You're close. The scatter and scatterm functions link colors to the current colormap of the figure. So you'll have to set the colormap. Using my rgb function it's pretty straightforward:

scatter(rand(100,1),rand(100,1),50,rand(100,1),'filled');
colormap(rgb('light pink','medium pink','dark red'))
