Are the DS game cartridges for Pokemon Diamond, Pearl, and Platinum reddish?

Question

Do all the fourth generation Pokémon games such as Pokémon Diamond, Pearl, and Platinum use infrared connections like the remakes for Pokémon Heartgold and SoulSilver? Or do Pokémon Diamond, Pearl, and Platinum not use infrared connections?

Answer 1

Diamond, Pearl and Platinum Cartridges are grey. The black HGSS carts were a special edition thing exclusive to HGSS and BW/2.

They both use infrared connection.
