Hi Paul, You could try using the tint feature built into Roll20. That can often give acceptable results. If not, you will need to alter it on your own. With many marketplace tokens, you are given the ability to download them to your own computer. Once you have the file locally, you can use any graphics editing program (such as Photoshop or the GIMP) and color shift the token to the desired hue. Different programs will have different commands for this, you may need to consult a manual or online help site.
