Week 3 Ex. 1 cookies

I have set my hue clocks as example shows and find I can not
take the yellow cast out of the picture.I have to agree with Joe S
in that the plate is the problem with the yellow color being
transmitted through it making the cast difficult to change

That certainly is the point.  The plate is yellow in this image even though you see it as clear.  the real question Mike was looking for opinion on was...Do you need to correct it out??

I like Fritz's answer so far.  The plate is absorbing UV and subsequently blue as well.  It is subtile but it is real...

The cookies are really an example of an image that does not have much of a cast.  Placing a hue clock on the shadowed and un-shadowed part of each cookie, as well as the background is a way to verify this, but there is no need to fix anything.  It's an example of the kind of image that we want to approach, as closely as possible, when color correcting a mixed lighting situation such as blue shadows.
