Teorie barev je r\u00e1mec, kter\u00fd je z\u00e1kladem pro pou\u017e\u00edv\u00e1n\u00ed barev v um\u011bn\u00ed a designu, slou\u017e\u00ed jako vod\u00edtko pro tvorbu barevn\u00fdch palet a usnad\u0148uje efektivn\u00ed komunikaci sd\u011blen\u00ed designu na estetick\u00e9 i psychologick\u00e9 \u00farovni. <\/p>\n\n\n\n

Modern\u00ed teorie barev je z velk\u00e9 \u010d\u00e1sti zalo\u017eena na barevn\u00e9m kruhu Isaaca Newtona, kter\u00fd vytvo\u0159il v roce 1666. Z\u00e1kladn\u00ed barevn\u00fd kruh zobrazuje t\u0159i kategorie barev, tj. prim\u00e1rn\u00ed barvy, sekund\u00e1rn\u00ed barvy a terci\u00e1rn\u00ed barvy. Pokud si pamatujete, \u017ee jste se o nich u\u010dili v hodin\u00e1ch v\u00fdtvarn\u00e9 v\u00fdchovy, dob\u0159e jste ud\u011blali - z\u00e1klady nauky o barv\u00e1ch jste ji\u017e pochopili! <\/p>\n\n\n\n

Sekund\u00e1rn\u00ed barvy<\/em><\/strong> jsou oran\u017eov\u00e9, fialov\u00e9 a zelen\u00e9. Jin\u00fdmi slovy barvy, kter\u00e9 lze vytvo\u0159it kombinac\u00ed jak\u00fdchkoli dvou ze t\u0159\u00ed z\u00e1kladn\u00edch barev. <\/p>\n\n\n\n
