In a large saucepan, heat the oil over medium heat. Add the red curry paste, lemongrass, kaffir lime leaves, and turmeric powder and cook until fragrant, about 2 minutes.
Add the coconut milk, fish sauce, and sugar to the saucepan and bring to a boil. Reduce the heat and let simmer for 10 minutes.
Add the shrimp and red and green bell peppers to the saucepan and continue to simmer for another 5-7 minutes, or until the shrimp are fully cooked and the sauce has thickened.
