as there doesn't appear to be very much yellow in the pink coloured m&m you might not get a very strong yellow by only altering selective colour
if you have layers in elements, add a new layer, make a circle around the m&m, on the new layer fill the circle with a bright yellow, change the new layer mode to multiply, burn or whichever gives you the best end result
hah ! boy is my color off. guess its time for an eye check. the pink was a yellow m&m but yes there isnt much yellow. I am thinking i probably would have been better picking out different colored m&ms for the picture. I am going to re-post the adjusted picture on my page. Check it out and tell me if it looks better and what else I need to do to it.
well maybe i am going to re-load it . this computor illiteracy is killing me. i saved the changes in photoshop but it is a blank file. will work on it here
you can make that pink one yellow if have "hue and saturation". In the drop down menu, select red the play with the sliders, should make it yellow no problem.
Retaking the photo with a yellow one would be better though.
