If you have manually coloured the cell yellow, then you cannot do what
you want to do with a standard formula (you could use a user-defined
function). However, if the yellow colour is the result of conditional
formatting, then you can apply the formula for that to the cell to
return "Caution".

Hope this helps.

I want to write a function that will enter text in a cell if a different cell
has yellow fill color.

Like this:

if cell A1 is yellow then put the text "caution" in this cell that has
the formula in it *[=if(A1=yellow,"caution", "")]
