To solve the problem of determining the color on the face opposite to 'Red' on a dice, we need to use the concept of opposite faces in dice configurations. Given two positions of the same dice, let's identify the pattern:

From the first dice configuration:

• Visible colors are: Red, Pink, Blue.

From the second dice configuration:

• Visible colors are: Blue, Pink, White.

In both configurations, the common visible colors are Blue and Pink. This implies that Blue and Pink are adjacent to each other on the dice, and thus cannot be opposite to 'Red'.

Now, since Blue and Pink are adjacent to each other, and both configurations show different third colors (Red in the first and White in the second), it implies that:

• White must be opposite to Red, as this is the only configuration where a third color appears in two different visible settings alongside consistent colors.

Therefore, the color opposite to 'Red' is White.

Conclusion: The correct answer is White.
