Twenty Eleven: "Add Citation" Text Color issue in Pullquote Block

[kajalgohel]

In Twenty Eleven Theme, when we add Pullquote block in editor side, and choose text color, We can see that the text color is reflected for "Add quote" and "Add citation" text.But when we see the same Pullquote block at front side, text color for "Add citation" text is not reflected.

Steps to replicate:
1: Activate the Twenty Eleven Theme
2: Add Pullquote block
3: Enter some Text for "Add quote"
4: Enter some Text for "Add citation"
6: Choose Text color
7: Save Page/Post
8: View the page/post at front side

For better understanding I provide video attachment link.
