You'll need a rather generous definition of "yellow."

I liked this task because it helped me to understand the a and b curves in Lab.

It is actually more simple than you have it...
It should take only 1 move in LAB.

Think Parabola. How about a nice green...

But...the lesson says, "This requires only one pass in Lab mode, with changes to all three curves."

Jay...

I cannot give it away just yet...I showed you how to make a nice emerald green.
The yellow is a variation on a theme.

This is one exercise where you really learn the power and speed of LAB please try it again.
Think color mixing and how would you get yellow out of red??
Or maybe.....

There is a way in HSB....Play around and see what you find....

I don't know how to do it with one move in Lab. But I had some luck with HSB:

Jay,
You kicked it's butt in HSB good work..

LAB is a three move operation 1 on each channel and youdo not get as good a result.

I'm enthusiastic after this lesson because I think I understand the Lab and HSB curves now.

Cool..I like it when the light come on...
I'm hoping I had some impact...but I am glad you are getting more comfortable with the other spaces...
