Painting a regular wall

Hello all!
Hope all is well with you folks.
A painting newbie here.

I am planning on painting a room in my house. The issue is that the color of the walls is a very "dark and gloomy dark blue".
I would like to paint the room light pink.

Do I have to first paint the room regular white and then paint it light pink or can I directly paint the walls light pink over the gloomy dark blue?
I am asking this because I am scared the gloomy dark blue background will some how mix with the light pink and make the walls look purplish blue ( pink + dark blue = purplish blue ).
I remember as a kid, when i mixed 2 water colors, i ended my a third surprise color. That's the reason why i am asking this question.
Thanks for the replies!!!

 

The problem is that it's not likely that your new color will completely "cover" the old color, resulting in some of that color being seen through the paint. When painting over dark or contrasting colors, it is often wise to prime the walls with a white primer before you are ready to paint. This essentially gives you a clean slate to start from. To do a perfect job, your new wall color will take a minimum of 2 coats.

 

So are you saying i need to do one white coat and 2 light pnk coats for a total of 3 coats or should i do 1 coat of white and 1 coat of light pink? Thanks

 

Primer, followed by 2 coats. A total of 3 coats. If you are happy with 1 coat of light pink that is up to you. But to the critical eye, a good painter would likely be able to see that it didnt get 2 coats of light pink.

 

Dont fall for the one coat statements unless you really dont care for how the wall will look.

When painting the first coat is for coverage (color) and the second coat is for finish (smooth finish).

An entirely different topic is paint quality, you get what you pay for and nothing good comes from a BBS (Big Box Store)!

 

Pinks and yellows have the worst coverage. I agree with priming the wall first. It will probably take 2 coats of pink to get complete coverage.
