photonegative

/fˌoʊtoʊnˈɛɡətˌɪv/ adj

having a negative phototropic or phototactic response; repelled by light

Word Origin From Greek phōs 'light' and negative from Latin negare 'to deny' — photonegative means 'light-denying,' describing materials that react negatively to light. Negative comes from neg- (no) plus -ative, so literally 'saying no.' Related words: negate, negation, renegade (one who denies), deny. The PIE root *ne- 'not' is the ancient no.
