Given input-output grid pairs as reference examples, carefully observe the patterns to predict the output grid for new test input. Each pair follows the same transformation rule. Grids are 2D arrays represented as strings, with cells (colors) separated by spaces and rows by newlines.
Here are the input and output grids for the reference examples:
Example 1
Input:
Black Yellow Yellow Yellow
Purple Yellow Yellow Yellow
Black Yellow Yellow Yellow
Black Yellow Yellow Yellow

Output:
Black Yellow Yellow Yellow
Purple Purple Purple Purple
Black Yellow Yellow Yellow
Black Yellow Yellow Yellow


Example 2
Input:
Black Green Green Green Green Green Green
Pink Green Green Green Green Green Green
Black Green Green Green Green Green Green
Black Green Green Green Green Green Green

Output:
Black Green Green Green Green Green Green
Pink Pink Pink Pink Pink Pink Pink
Black Green Green Green Green Green Green
Black Green Green Green Green Green Green


Example 3
Input:
Black Green Green Green Green Green
Black Green Green Green Green Green
Orange Green Green Green Green Green
Black Green Green Green Green Green
Black Green Green Green Green Green

Output:
Black Green Green Green Green Green
Black Green Green Green Green Green
Orange Orange Orange Orange Orange Orange
Black Green Green Green Green Green
Black Green Green Green Green Green


Here is the input grid for the test example:
Input:
Black Gray Gray Gray
Pink Gray Gray Gray
