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
To convert from decimal code, divide by 255.
% equals
[ 0.066667 0.066667 0.066667]
The color gray is
% RGP TRIPLE %CSS3 proposed standard name:
[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.

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

works perfectly.
thanks for the link too, really appreciate it
