[webvtt] Figure 1: use more accessible colors (#487)

spoeschel has just created a new issue for https://github.com/w3c/webvtt:

== Figure 1: use more accessible colors ==
The green/orange colors in [figure 1 (§ 3.4)](https://github.com/w3c/webvtt/blob/gh-pages/webvtt-region-diagram.png) are a bit difficult to distinguish for people with red-green colour blindness (like me). E.g. the following colors could be used here, changing orange to red ([source](https://github.com/w3c/imsc/issues/391#issuecomment-397728217)):

- `#50FF50`
- `#FF5F5F`
