Getting colors using RGB values w/ scatter3

I am trying to get grey colored plot points on my 3D scatter plot, I am unfamiliar with scatter3. From the error messages I am getting using the conventional method (on a regular plot, shown below) - I am assuming there should be an established color vector.

This is what I have currently

scatter3(X,Y,Z,'filled', c, [17 17 17]);

rgb triplets are normalized between 0:1

https://www.mathworks.com/help/matlab/ref/colorspec.html

To convert from decimal code, divide by 255.

[17,17,17]./255
% equals
[ 0.066667     0.066667     0.066667]

The color gray is

% RGP TRIPLE                           %CSS3 proposed standard name: https://www.w3.org/TR/css-color-3/
[0.5          0.5          0.5]        %gray
[0.82422      0.82422      0.82422]    %light gray
[0.75         0.75         0.75]       %silver
[ 0.66016      0.66016      0.66016]   %dark gray
[0.14844      0.14844      0.14844]    %mine shaft
[ 0.4375          0.5       0.5625]    %slate gray

See the rgb() function on the file exchange for RGB triplets to many different colors.

To apply that to scatter3; here's how to color all points gray and filled.

scatter3(x,y,z,[],[.5,.5,.5],'filled')

Thanks Adam,

When I am including this in the scatter3 code, what would the syntax be?

I currently have, but it is incorrect

scatter3(X,Y,Z,'filled', 'Color', [0.5          0.5          0.5] );

See this example

https://www.mathworks.com/help/matlab/ref/scatter3.html#btr5_il-1

scatter3(x,y,z,[],c)

c is the matrix of rgb triplets. If you want all points to be the same color and filled,

scatter3(x,y,z,[],[.5,.5,.5],'filled')

[Hans123]

works perfectly.

thanks for the link too, really appreciate it

Glad I could help!
