Need help with sprite/color collision

[Chase]

Hello, I started learning App Inventor last week and made a game that allows the player to draw a maze and then guide a ball through it with the accelerometer. My issue is the detection when the ball sprite touches either of the colors of the line or hole. I attached a copy of the .aia file and a picture of the blocks. Any help would be greatly appreciated!
