Waa maxay booska midabbaarka sheybaarka iyo sidee u kala duwan yahay LCH?

Booska midabka sheybaarka (caelb) iyo xiinka midabka leh (celchch) waa labaduba moodel midab leh oo ku saleysan aragtida muuqaalka aadanaha, laakiin way ku kala duwan yihiin sida ay u matalaan midabada.

Qolka Lab

Booska midabka shaybaarka wuxuu ka kooban yahay seddex qaybood:

L (Friends): waxay matalaysaa iftiinka midabka, oo u dhexeeya 0 illaa 100.

A (casaan-cagaaran): Waxay ka dhigan tahay booska u dhexeeya casaanka iyo cagaarka, oo leh qiimayaal wanaagsan oo muujinaya qiimayaasha cas iyo taban oo muujinaya cagaar.

B (huruud-buluug ah): waxay matalaysaa booska u dhexeeya jaalaha iyo buluugga, oo leh qiimayaal wanaagsan oo muujinaya qiyamka jaalaha iyo taban ee muujinaya buluug.

Faa'iidada booska midabka shaybaarka waa madax-bannaanideeda aaladda, oo u oggolaanaya sharax aad u sax ah oo ah dhammaan midabada u fiirsada isha bini-aadamka
LCH midab

Booska midabka leh ee LCH waxaa laga soo qaatay booska shaxda shaybaarka oo adeegsanaya isku-duwaha Polar si ay u matalaan sifooyinka midabka si isdaba joog ah. Waxay ka kooban tahay qaybaha soo socda:

L (Light): la mid ah sida qolka shaybaarka, oo matalaya iftiinka midabka.

C (chroma): waxay matalaysaa fadhiyada ama xoojinta midabka.

H (HUUE): Waxay ka dhigan tahay booska midabka ee midabka midabka, oo u dhexeeya 0 ilaa 360 digrii.

Booska midabka leh ayaa faa'iido leh maxaa yeelay waxay si dhow ula jaan qaadayaan sharraxaadda maalinlaha ah ee midabka, sameynta sixitaanka midabka si fudud in la fahmo oo la xakameeyo
Kala duwanaansho

Wakiilo:

Shaybaarka: Isticmaalka CartEsian-ka wuxuu matalaa inuu matalo midab, oo loo kala qaybiyey nabarro (L), casaan-cagaaran (a), iyo jaalle-buluug (b).

LCC

Dawladnimada:

Shaybaarka: Ku habboon oo ku habboon codsiyada sayniska iyo farsamada, oo bixiya sharraxaad midab oo sax ah.

LCC: dareen badan oo dareen leh aragtida muuqaalka aadanaha iyo sharraxaadda maalinlaha ah, taasoo fududeyneysa in la fahmo.

Codsiyada:

Shaybaarka: Si ballaaran loo isticmaalo iyadoo la adeegsanayo muuqaalka muuqaalka, daabacaadda, iyo maaraynta midabka.

LCH: sida caadiga ah loo isticmaalo sixitaanka midabka iyo isbarbardhiga, ku habboon bilowgayaasha iyo xaaladaha u baahan sharraxaad midab leh

Sida loo beddelo shaybaarka illaa lch

Si aad ugu beddesho qiimayaasha iftiinka midabka sheybaarka leh qiimayaasha booska ee midabka, raac talaabooyinkan:

Nalalka (L): Khasaaraha (L) qiimaha (L) waa isku mid labada shay iyo lch.

Chroma ©: Xisaabi Chroma © adoo isticmaalaya xididka laba jibbaaran ee isugeynta labajibbaaranaha a iyo b.

C = sqrt (a ^ 2 + b ^ 2)

Hue (H): Xisaabiso Hue (H) adoo adeegsanaya awooda Arctus-ga ee B ee loo qaybiyay a, oo u beddelo natiijada shahaadooyinka.

h = arctdan (b / a) * (180 / π)
