어둡다

Why being clueless about machines is talked about as darkness
The picture Light drains away and a cover comes down, so the inside can no longer be seen. 어둡다 is light draining until the inside is covered; 밝다 is light coming in until the inside shows.
Where the picture shows up in 어둡다
-
light drains, the room is covered
전구가 나가서 방이 어두워요.
jeon-gu-ga na-ga-seo bang-i eo-du-wo-yo
The bulb died, so the room is dark.
The bulb snaps off and everything in the room is covered at once, leaving only outlines

black soaked into a colour
어두운 색 정장을 입으세요.
eo-du-un saek jeong-jang-eul i-beu-se-yo
Please wear a dark-coloured suit.
The fabric swallows the light instead of giving it back, so from a distance it reads as one solid mass
-
light sinking out of a face
오늘 사장님 표정이 어두워요.
o-neul sa-jang-nim pyo-jeong-i eo-du-wo-yo
The boss looks gloomy today.
The light that was up in the face sinks away, and shadow settles in from under the eyes down
-
the road ahead is covered
올해 장사 전망이 어둡습니다.
ol-hae jang-sa jeon-mang-i eo-dup-seum-ni-da
The outlook for business this year is bleak.
Fog lies over the road you have to walk, and a few steps on there is nothing to see at all
The picture is a cover over the eyes that look at what's coming.
-
no lamp on in that corner of the head
저는 기계에 어두워서 좀 도와주세요.
jeo-neun gi-gye-e eo-du-wo-seo jom do-wa-ju-se-yo
I'm clueless about machines, so please help me.
Only the corner of the head where machines are kept has its lamp off, so groping about brings nothing into your hand
'~에 어둡다' pictures one field alone with the light switched off.
All of it in one picture
어둡다 is one picture: the light drains and a cover comes down. The bulb dies and the room is covered; black soaks into cloth and you get a dark colour. Light sinks out of a face and the expression is 어둡다; the road ahead is covered and the forecast is 어둡다. And if one corner of someone's head has no lamp on, they are 'dark' in that field.
