Hi Bharathi,
You can use 'color' linespec to change the color of your velocity vectors. For your reference I have written a code. You may take help of it.
[x,y] = meshgrid(0:0.2:2,0:0.2:2);
u = cos(x).*y;
v = sin(x).*y;
figure
quiver(x,y,u,v,'color',[1 0 0])
The above code will give you red color velocity vectors. By changing the linespec for eg. [1 1 0], it will give you yellow color.

Hi Priyanshu,
I guess that Bharathi meant that color could change depending on velocity magnitude, similarly to what happen in contour plot.
Colorbar should help reading magnitude related to color, if this is possible
