How can I get the colors in Chinese?

If you mean how you study colours in Chinese, then maybe this will help you :

Colours in chinese is 颜(yán)色(sè)
Some basic colours in Chinese
黑(hēi)色(sè)
白(bái)色(sè)
红(hóng)色(sè)
蓝(lán)色(sè)
绿(lǜ)色(sè)
黄(huáng)色(sè)
橙(chéng)色(sè)
灰(huī)色(sè)
棕(zōng)色(sè)
粉(fěn)红(hóng)色(sè)
金(jīn)色(sè)
银(yín)色(sè)
etc

you can also put 浅(qiǎn) and 深 (shēn) in front of those colours as combination
浅(qiǎn)颜(yán)色(sè) means light colours
深(shēn)颜(yán)色(sè) means dark colours
When you combine
深(shēn)红(hóng)色(sè) means dark red colour
浅(qiǎn)红(hóng)色(sè) means light red colour

I watch Chinese TV serials. The pronunication is the best. After finding your favourtie TV serials, you may repeat watching and learn the dialogue there from the actors.

Reading is important too. Need to keep reading frequently.

Enjoy learning !!

You can try to learn colors like this : sky + blue ，sea + blue, lemon+ yellow, ginger + yellow, watermelon+ red, apple + green, grape + purple, etc

What do you mean by "get the colors"? Do you mean studying them?
