 Thanks, Jim... 
  
I bought a tube of Naples Yellow a few weeks ago 
and just used it as a first layer of a monochrome print. A beautiful 
color... 
  
Yellow Ochre's opacity would be ok, since I usually 
lay down yellow first.

  Paul, Cad Yellow Pale is a very high chroma hue, in this case, 
  a very bright and intense yellow. You could try Yellow Ochre, but it is an 
  opaque pigment, or try Naples Yellow or even Raw Sienna. These last two have 
  nice transparent properties so they would be better than the Ochre.

    Hi all... 
      
    After making several tricolor gums, I am 
    feeling that my yellow layer is a bit on the heavy side. Where I am 
    expecting muted yellow-browns in my final print, I am seeing a brighter 
    shade slightly on the garish side. I see this with oranges as well. Where I 
    expect a more terracotta color I am seeing a brighter orange. 
      
    How can I correct for this? Should I mute the 
    yellow by doubling the gum arabic in the pigment mixture? Or expose that 
    layer less? 
      
    I can also change colors...at the moment I use 
    Cad Yellow Pale, along with Quin Red and Phthalo Blue RS, all Daniel Smith 
    pigments. Maybe toning the Cad Yellow down with something like Raw Sienna 
    will mute the vibrancy... 
      
    Thanks!
