Hi this is our first time painting our wall, and we just realize that the paint needs to be tinted before use.
We just moved into a new home and there is a blue wall which we want to paint it into the same color with other walls in the house.

Problem is there are many names for different colors that make us dizzy, do we really need to take a sample chip of wall and bring it to Bunnings for color matching?
And how about we take some photos of the wall under natural light, and bring it to Bunnings? We aren't not deadset on getting perfect match, similar is good enough for us.
Is the process like the following steps?
1) We take this white low sheen product to the counter

2) Then we show the photo to the Colour Consultant
3) And Colour Consultant will tint the white low sheen paint to the color we want?
Is this how it works? Sorry for the silly question, we are still learning.
