Description

This PR updates the README to document a known limitation with text colors (foreColor).

Alpha values (e.g. rgba(...) or hex with transparency) are not fully supported because the WebView relies on the deprecated <font> tag. This leads to inconsistencies such as:

  • No real transparency being applied (colors just appear darker).
  • Some cases rendering unexpected colors (e.g. rgba(0,0,0,0) displays as red).

It is recommended to use solid colors only.
For a detailed explanation, please refer to the related issue: #410

Changes in this PR

  • Added a note in the README about the limitation of alpha values in foreColor.
