How can I Ventilate 2 rooms that share the same air source?

Question

I have 2 rooms that are beside each other,a blue and pink room. The pink room gets very hot in the afternoon but the blue room stays moderately cool. The pink room has an exhaust and the bule room has a fan that can suck or blow air out. A wall fan is installed in the pink room but it's still hot inside. The only source of cool air is from the kitchen which is connected to the blue room. How can i ventilate the pink room? Should i add another exhaust fan in the pink room? What should i do? I'll be thankful for any solution that u can give...
