title: Meshlab: how to select vertex by color
body: <p>I want to select vertex by color. At the moment I want to select the cells with (R,G,B)=(0,0,0). What function should I write?</p>
  
  <p>r=0 and g=0 and b=0 doens't work.</p>
  
  <p>And if I want to pick (R,G,B)=(255,255,255)? Or any other combination?</p>
  
  <p>This question might be strange but I guess these colors don't vary between 0 and 255. They seem to vary between 0 and 1 instead.</p>
  
  <p>Regards</p>
