Imbwa dzinoona mavara, asi iwo mavara aanoona haana kupfuma kana kuwanda seayo anoonekwa nevanhu.

Maziso evose vanhu uye imbwa ane akakosha mwenje inobata maseru anonzi macone anopindura ruvara. Imbwa dzine makoni mashoma pane vanhu, izvo zvinoratidza kuti yavo yekuona mavara haizove akapfuma kana akasimba sesu. Nekudaro, hunyengeri hwekuona ruvara hausi kungova nemakoni chete, asi kuve nemhando dzakasiyana dzekoni, imwe neimwe yakatarwa kune akasiyana marefu evhenekeri. Vanhu vane mhando nhatu dzakasiyana dzekoni uye chiitiko chakabatanidzwa cheichi chinopa vanhu huwandu hwakazara hwekuona kwemavara.

Mhando dzakajairika dzevanhu colorblindness dzinouya nekuti munhu arikushaiwa rimwe remhando nhatu dzemakoni. Nemakoni maviri chete, munhu wacho anogona kuona mavara, asi akawanda mashoma pane munhu ane zvakajairika kuona kwemavara. Iyi ndiyo mamiriro kune imbwa dzinongovawo nemhando mbiri dzemakoni.

Kune akawanda bvunzo bvunzo, imbwa dzakaratidzwa matatu mwenje mapanera akateedzana, maviri emapaneru aive iwo iwo iwo iwo mavara, nepo chechitatu chakasiyana. Basa rembwa kwaive kutsvaga raive rakasiyana uye nekutsikirira iro jira. Kana iyo imbwa yaive yechokwadi, iye akapiwa mubairo nerubatsiro urwo komputa rwakaunzira mukombe pazasi pepaneru.

Neitz akasimbisa kuti imbwa dzinonyatsoona ruvara, asi akawanda mavara mashoma pane akajairwa vanhu. Panzvimbo pekuona muraraungu se violet, bhuruu, bhuruu-girini, girini, yero, orenji, uye tsvuku, imbwa dzaizozviona serima bhuruu, bhuruu yakajeka, grey, yero yero, yakasviba yero (rudzi rwebrown), uye rakasviba gireyi.
