Cov hlau nplaum tuaj yeem pom tseeb

Cov hlau nplaum yog tsim los ntawm ntau yam ntaub ntawv xws li hlau, cobalt, thiab npib tsib xee, uas muaj cov khoom siv hlau. Cov ntaub ntawv no tsis yog pob tshab, thiab yog li cov hlau nplaum tsis tuaj yeem pom meej meej hauv cov lus ib txwm muaj.

Txawm li cas los xij, muaj qee hom hlau nplaum uas tuaj yeem pom meej meej me ntsis. Piv txwv li, cov hlau nplaum neodymium feem ntau yog coated nrog ib txheej nyias ntawm npib tsib xee, uas ua rau lawv ci thiab xim hlau zoo li. Tej zaum qhov no tuaj yeem tsim qhov illusion ntawm qhov chaw ntshiab.

Tsis tas li ntawd, qee cov hlau nplaum yog tsim los siv cov ntaub ntawv ntshiab lossis cov ntaub ntawv zoo xws li yas lossis iav. Cov hom hlau nplaum no feem ntau siv rau kev tshaj tawm lossis ua cov khoom zoo nkauj.

Nws tseem tsim nyog sau cia tias cov hlau nplaum tuaj yeem ua tau ntau yam xim. Qhov no yog ua tiav los ntawm kev ntxiv pigments rau cov khoom siv los ua cov hlau nplaum. Yog li, thaum cov hlau nplaum tsis tuaj yeem pom meej meej, lawv tuaj yeem tsim nyob rau hauv ntau yam xim kom haum rau qhov sib txawv nyiam thiab cov kev xav tau.
