"We have found good yellow color for equipment. While the Vallejo Golden Yellow we offer (70948) is a good, basic yellow, we have searched for something with a little more vibrant yellow pigment. We found it in the Vallejo Game Air Gold Yellow (72707). This is a 17ml bottle of pre-thinned color - ready for air brushing. Because it is already formulated for air brushing, it cannot be brushed on and should be applied to a thorough, even coverage of primer (use white primer for a closer to exact color representation or the gray primer for a darker surface color). For a more aged look and feel to your vehicles (sun-bleached), use the Golden Yellow (VJ70948) and for a newer surface color, mix in this new Game Air Gold Yellow or use it as-is."
