How to change colors in Scatter plot?

How to change colors in Scatter plot? I need to change the default colors "dark red and dark blue" into "light red and light green"

x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
RGB = [255 153 153]/256 ;
RGB = [204 204 255]/256 ;
scatter(x,y,[],RGB)

Choose your required color RGB array.

Thanks for your help My data has 2 values. Each one of these values are represented in color. I need to change the colors of these 2 values but I still need to get 2 colors

[KSSV]

clc; clear all ;  
x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
RGB1 = repmat([255 153 153]/256 ,length(x)/2,1) ;
RGB2 = repmat([204 204 255]/256 ,length(x)/2,1) ;
RGB = [RGB1 ; RGB2] ;
scatter(x,y,[],RGB)

Thanks alot for your help

my data is:

0.385500   -0.116750   1
-0.575000  0.050250  2
0.004250  -0.788250  1
0.438250  0.544500  2
0.460250  0.610250  1
0.505000  0.110750  2

The first column is x, the second is y and the third is the output (z)

I'm using

scatter (x,y,5,z,'filled')

This gave me all the z data as function is x, y ( which what I need) but with 2 colors hard to be differentiated.

I need to change the default colors with colors easy to differentiate between them

When I use your function

RGB1 = repmat([255 153 153]/256 ,length(x)/2,1) ;
RGB2 = repmat([204 204 255]/256 ,length(x)/2,1) ;
RGB = [RGB1 ; RGB2] ;
scatter(xX,yX,zX,,RGB)

It gives me an error "Expression or statement is incorrect "

I don't know why this is incorrect

Thanks a lot for your time and help

You missed the point size parameter

scatter(xX, yX, 5, RGB, 'filled')

[Walter Roberson]

I recommend:

coltab = [255 153 153; 204 204 255];
RGB = coltab(z(:), :);
pointsize = 5;
scatter(x, y, pointsize, RGB, 'filled');
