Thread Subject: define color

How do I define custom colors in matlab ??
The documentation for the color commands are almost useless ..
I've tried: set(grey,'Color',[0.4,0.4,0.4]) but when I put 'grey' in my plot options, my lines are not grey.

Uhhh, why not

grey = [0.4,0.4,0.4];
plot(x,y,grey)

Bruno

It doesn't work for me:

>> x=1:10;
>> y=x*2;
>> grey=[0.4,0.4,0.4];
>> plot(x,y,grey);
??? Error using ==> plot
Data must be a single matrix Y or a list of pairs X,Y

>> plot(x,y,'grey');
??? Error using ==> plot
Error in color/linetype argument

Opps, try to replace the plot command by

plot(x,y,'Color',grey);

% Bruno

Perfect! Thanks so much!
