Just a few more tests to confirm inter-reactions.
Top mandrel - Orange Punch, encased - does show lighter. (Thicker encasing to the right).
Second Mandrel - Orange punch and Sunshine and Lemon Meringue. What a happy, festive colour combo!
Third Mandrel. Turquoise and Lemon Ice. Ok. I'd say that confirms the Yellow Ice as a Very Light Ivory!
Fourth Mandel. Sunshine and Lemon Meringue with Turquoise. Note, the dark reactive border.
