I am starting to gather stuff to start dipping tubes. my question is the coloring. I can find the color that I am looking for and wanted to know if anyone has made a mustard color tube. what colors where used to make it. thanks for the help new to the page 

Go to Tackle Underground and see if you can get help there. That is where you may find which colors and in what amounts you need to create that color. I'm guessing it is yellow and a little black or maybe a little brown.

Like smalljaw stated that is probably your best option.  Be sure to look at the soft plastics cook book.  It has hundreds of recipes for all kinds of colors.  

thanks guys for the fast reply. thanks again
