A clear and concise description of what the bug is.

The change of tone colors described in https://krmanik.github.io/Anki-xiehanzi/docs/customization/change-tone-color

doesn't apply to all parts of the card.

E.g., sentences are still using the old colors.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Set Tone Colors as described in the guide by changing the template lines:

:root {
    --tone-1: #f44336;
    --tone-2: #ff9800;
    --tone-3: #4caf50;
    --tone-4: #2196f3;
    --tone-5: #607d8b;

Expected behavior
A clear and concise description of what you expected to happen.

All colors on the cards should change. But only the stroke color and the main character displa change colors. Meaning and sentences still use the old colors.

I seem to have found a fix, after looking at the HTML for the meaning and sentence fields.

Changing the definitions of the text-colors from:

.text-color1 {
  color: var(--pinyin-color);
}

.text-color2 {
  color: var(--traditional-color);
}

.text-color3 {
  color: var(--meaning-color);
}

.text-color4 {
  color: var(--simplified-color);
}

to

.text-color1 {
  color: var(--tone-1);
}

.text-color2 {
  color: var(--tone-2);
}

.text-color3 {
  color: var(--tone-3);
}

.text-color4 {
  color: var(--tone-4);
}

.text-color5 {
  color: var(--tone-5);
}

seems to fix the issue without any obvious negative consequences for me.
