Silk Screening uses a fixed number of colors, between 1 and 5 printed on another, for a total of 2 to 6 color designs.
Each Screen and color costs extra money, and most silk screened shirts are 1 or two colors. To do get variations, graduations can be done with dots. Lots of dots.
This sample shows a vector design with color graduations, and one way to do that in white on black, a 1 color silk screened design.
