How can I get a fading look on fondant without using an airbrush? The cake is three tiers. I want to start from the top with blue and fade all the way to the bottom tier into a dark green. Thank you for help in advance!

The only thing I can think of it to color your fondant or BC in graduating shades for each tier to achieve something similar.

So your bottom tier could be colored dark, middle tier medium and top tier light (or vice versa) of whatever color you choose.

You could add accents to draw your eye up or down the cake and add to the "flow" of one color to another, like a cascade of flowers going down the side, or dots building from heavy to light in number. Swags of fondant coming down each tier to the next. Possibilities are endless.


Here's an example (not my work but found on CC) of what I'm talking about. Each tier you could color the fondant and then apply something (like the lace and flowers) to draw the eye up and down the cake.
Can work for BC too.
