Make a plot with markers that look something like this image. But i want to be able to control the colors. Sometimes make it fully one color, some times left side is colored, sometimes right side is colored.

This is not built in functionality, at least not that I'm aware of. You can find a list of supported markers here.
You could create your own function to create and add custom markers to your plot. Here is a simple example. It's definitely not robust, but could get you started.
x=1:5;
y=[3 1 4 5 3];
plot(x,y)
addMrkr(x,y,.1,'r','g')
axis equal
function addMrkr(x,y,R,cL,cR)
% x,y are row vectors of line points
% R is radius
% cL,cR are colors of left/right semicircles
% left
th = linspace(pi/2, 3*pi/2)';
xL = R*cos(th) + x;
yL = R*sin(th) + y;
hold on
patch(xL,yL,cL);
% % right
th = linspace(pi/2, -pi/2)';
xR = R*cos(th) + x;
yR = R*sin(th) + y;
patch(xR,yR,cR);
hold off
end
