Yes take the numbers into paintshop pro.
Well from that earlier picture with all the windows opened, you will see the palette and the transparency windows (on the right, one on top of the other). You will notice these correspond to each other, so when the transparency is black that particular colour will be invisible, and when it's white it will be visible. With all the other degrees of greyness are the areas around the number so that the edges are rounded and look real, so they are semi transparent.
EDIT: to get the palette open in paintshop pro, go to the palette or colour range, save that as a .pal, then edit and load that when you are done.
