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:
Orange Red Orange Pink Blue
Green Yellow Pink Green Red
Yellow Orange Green Pink Pink
Pink Yellow Red Blue Orange
Yellow Green Orange Pink Green

Output:
Yellow


Example 2
Input:
Yellow Red Red Orange Orange
Blue Orange Pink Red Red
Yellow Blue Blue Orange Green
Green Orange Green Red Green
Pink Blue Red Yellow Red

Output:
Gray


Example 3
Input:
Yellow Orange Pink Green Green
Pink Yellow Blue Yellow Yellow
Blue Red Blue Yellow Red
Pink Pink Red Green Red

Output:
Yellow


Here is the input grid for the test example:
Input:
Yellow Pink Green Pink Red
Red Orange Green Pink Pink
Red Pink Red Red Blue
Pink Red Pink Yellow Green
Orange Green Pink Green Green


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
