One way:
fit a table:

A B C
------------------------------
RED YELLOW GREEN
------------------------------
Apple Banana Grapes
Peer

Give a name: the range "Apple" is called "RED"; the range "Banana" is called "YELLOW"; the range
C2:C3 is called "GREEN".
Then, in column A put the validation: A1:C1.
The last step: in column B put the validation:
=INDIRECT(A1).
This way, once is selected in A1 "RED", automatically in B1 is allowed only the value "APPLE", and
so on.
