The Wonderland Board

I have a feeling this level should be one of the easiest but I just cannot figure out the last section where you have to get the aqua key then the pink key. I've done everything, even gone back to re-do the first sections thinking if I did something different there it might change the last part but no luck. If you can give me a hint rather than a solution that would be great. I also checked the forums for this one and didn't see it which means I must be the only numbskull who can't get it......UGH!

Hint #1 wrote: The first two color teleporters you use come in rainbow order. (ie, red then orange, or orange then yellow, or yellow then green, ... etc.)

Hint #2: wrote: To teach one teleporter, you will have to take a diagonal step.

Hint #3 - Not cryptic: wrote:First teleporter to use is:

Orange.

Hope that helps.
