You are trying to create an array without specifying its size. If the size is dynamic, you should use pointers instead. type x[][]; is always an error, regardless of type. You can initialize your array though, int x[] = {10,11}; // ok or int[][2]={{1,2},{1,2},{1,3}}; // also works

You should specify the size of your array:

Color color[HEIGHT][WIDTH];

you're not specifying the size for the two-dimensional array as it seems. maybe that's causing the problem?

Your definition of color lacks sizes for the subscripts. Therefore, the compiler cannot determine how much space to allocate for color.
