Hi Kanaetochi Okiyi 👋

You'll want to have another look at the challenge what is being asked 🙂 You're trying to set the background color on the foodLabel but the task is to change the text color of both of those labels.

Let's continue to add color to MealActivity. In the onCreate() method, set the text color of foodLabel to Color.BLUE. Then set the text color of drinkLabel to Color.GRAY.

    foodLabel.textColor = Color.BLUE
    drinkLabel.textColor = Color.GRAY

Hope this helps 🙂
