white
'weiß' and 'bleich' can both describe a very light, colorless face. 'weiß' feels very direct and often strong: someone's face goes white because they are frightened or suddenly feel unwell. 'bleich' also means very pale, but it sounds a bit more descriptive and often somewhat more serious or literary. Both fit with fear, illness, or fright. In normal conversation, people also often say 'blass'; 'bleich' usually makes the impression stronger.
