Step 1: Careful observation of both patterns.
Both fractal images contain blue-colored patches, but the tones are neither clearly darker on the left nor clearly lighter on the right. The shading differences appear to be due to pattern density, not actual color tone.
Step 2: Comparing tone accurately.
When viewed closely, the blue regions in both patterns appear to have the same hue and same intensity, with no significant difference in brightness or darkness. Options (A), (B), and (C) do not correctly describe the visual observation.
Step 3: Conclusion.
Since none of the given statements about darker, lighter, or same tone are accurate, the correct choice is (D) None of the above options.
