Morphology

redout = red (semi-transparent) = out + red

Formed from the clear components 'red' + 'out', but the specialized medical/aviation meaning ('vision loss due to excess blood') is domain-specific and not obvious to general learners. [Postprocessing: moved 'out' from base_words to prefix]

Etymology

Redout is a modern aviation word made from the parts red and out, used as the opposite of 'blackout'. It names the brief reddening or dimming of your vision when too much blood rushes to the head, which is why it is called a 'redout'.
