For reference of the HP bar color:

The HP bar is 48 pixels long in both generations. The amount of pixels left in the HP bar approximately represents the current (HP / max HP) ratio of the Pokemon. In Gen 1, the HP bar turns yellow when it has 26 or less pixels, while in Gen 2, it will turn yellow at 23 pixels or less. In both generations the HP bar turns red at 9 or less pixels.
