Mitundu ya Achromatic

Mitundu ya Achromatic ili ndi malingaliro ofanana ndi mitundu ya chromatic.Zakuda ndi zoyera zimayimira mitengo ya yin ndi yang ya dziko lamtundu, zakuda zimatanthauza zopanda pake, monga chete kwamuyaya, ndipo zoyera zimakhala ndi mwayi wopanda malire.

1. Black: Kuchokera kumalingaliro amalingaliro, wakuda amatanthauza kulibe kuwala ndipo ndi mtundu wopanda mtundu.Malingana ngati kuwala kuli kofooka kapena mphamvu ya chinthu chowonetsera kuwala ndi yofooka, idzawoneka yakuda.Black imagwiritsidwa ntchito popanga toning popanga utoto komanso kusintha kupepuka (shading, shading) kwa mtundu.Mtundu uliwonse ndi wakuda kwambiri.
2. Choyera: Choyera ndi chisakanizo chofanana cha kuwala konse kowoneka, kotchedwa kuwala kwamtundu wonse.Titanium dioxide ndi yomwe imagwiritsidwa ntchito kwambiri poyera.Nthawi zambiri amagwiritsidwa ntchito kukonza kuwonekera kwa mapulasitiki pofananiza mitundu.Kuwonjezera titaniyamu woipa kungachepetse kuwonekera kwa mapulasitiki, ndipo nthawi yomweyo kumapangitsa kuti mtundu wa pigment ukhale wopepuka komanso wopepuka.kuzimiririka.Mtundu uliwonse ndi wopepuka kwambiri komanso umawonekera woyera.
3. Imvi: pakati pa zakuda ndi zoyera, ndi za kuwala kwapakati, ndi mtundu wopanda chroma ndi chroma wochepa, ndipo ukhoza kupatsa anthu kumverera kwapamwamba ndi kosaoneka bwino.Imvi ndi mtundu wosaoneka bwino kwambiri wamitundu yonse, ndipo umadalira mitundu yoyandikana nayo kuti upeze moyo.Ziribe kanthu kusakaniza kwakuda ndi koyera, kusakanikirana kwa mitundu yowonjezera, ndi kusakaniza mitundu yonse, pamapeto pake idzakhala imvi yopanda ndale.
