(#M40037419) INFOSYS QUESTION Guess the colours Keep an EYE

(3) Four people played cards, which had colors on both of their
sides. The colors on the two sides were different and no two cards had the same color combination. When the cards were distributed to them, they kept their cards on the table with one side per card facing up, of course. Each card holder knew the color of the hidden side of his card. They spoke up one by one as follows:
A: My card, showing Red above, has either Green or Blue color beneath
B: My card, showing Green above, has neither Green nor Blue color beneath
C: My card, showing Yellow above, has either Blue or Yellow color
beneath
D: My card, showing Blue above, has either Blue or Yellow color beneath
However, later it was found that exactly two of them were lying. Can you find who was lying and what were the colors on the hidden sides of each card?
