The color of the body of the cleco determines the drill size you use. The silver ones are 3/32 or #40 drill which is the best size for automotive sheetmetal as the holes are small, and easy to weld over.
Copper color is.1/8" drill or #30 drill size
Black color is #21 drill size
Brass color is #10 drill size.
Im an aircraft sheetmetal mechanic by trade. The larger the # the smaller the hole. I use the #40 silver clecos at home doing my automotive sheetmetal. They really seem to work the best. The wingnut type or draw clecos as they are called are pricey, but not needed for all situations. Check out the button or spring clecos. These require a pair of plyers to install or remove. The plyers are about $6.00, and the spring clecos are $4.20 a dosen. A have a bunch of these work great for hanging quarter panels, or pinning floor pans in place to weld em in . Since these are so cheap id stay away from used ones on evilbay.
