Steps to reproduce the bug

Go to Learn from your mistakes in a game and explore the moves of the game. On some moves translucent arrows of different colors are displayed. They are apparently too faint:

After the game is over in the option to learn from your mistakes the red arrows are very hard to see. so an option to have actually visible arrows would be nice.

A visible example:

<line stroke="#882020" stroke-width="0.125" stroke-linecap="round" marker-end="url(#arrowhead-pr8)" opacity="0.4" x1="-3.5" y1="2.5" x2="-3.5" y2="1.65625"></line>

What did you expect to happen?

This is a user request from LiChess Tools. Apparently he wants that opacity to be higher than 0.4

What happened instead?

Faint arrows.
