Sometimes painting on a wall come up with an awful and awkward look. It usually happens most when you make a combination of grey colour with different shades. As you expected, it would come out as a perfect grey, but the results come as a shiner. Now in this step, you have to learn how to make grey paint look less blue? In this article, I will explain the full method and the combination of grey paint with other colour shades.

Now we will mix different colours. After mixing, we will see what results will come out. Then we use the most effective colour to reflect less blue in grey paint. 

Why Grey Color turns blue?

When you paint grey colour, it can be turn out in 3 different undertone shades, like blue, green, and purple. As a result, it might look like these three colors because the undertone is missing in this colour.

Before making proper grey paint, you have to utilize it so that it will give you the desired results. 

Many factors impact your wall colour:

The direction of your room

The direction of your room will impact all the paint colours you painted. If you paint grey but either your direction is north face, then it will look bluer.

Colour effect  

If you contrast and mix dark brown and blue colour paint, it will result in a more dark brown colour. But opposite to this method, mix any light shade with Blue. It gives you lighter shades. The same thing happens with grey paint.

Light Reflectance value

It means that light effect more than anything. For a test, check what your paint colour will result in sunlight or daylight, and what will be the result in artificial or you desired room light? These both positions will reflect you two different shades in 2 different LRV. The range of LRV is from 0-100. It will reflect you how much lighter and darker shades will result from diverse light range.

The higher the range, the lighter will be the shade. This discussion means that if higher the range of LRV illumination, the grey colour might wash out.

Mass Tone/ Undertone

Mass tone means what colour you see when looking at the wall’s 1st time. If you are using any colour must choose an undertone closer to the mass tone. It will give you a more accurate result. The undertones of grey colour are blue, green, and red, as I mentioned above. Now the contrast of the green colour is yellow while the contrast of the red is pink. Undertone will ultimately affect how cooler or warmer your wall will look.

This colour is a medium grey colour with Blue. If you are in a north-facing direction, then whatever grey you paint will reflect as blue.


Flooring also impacts on wall paint directly. As if you have darker the floor, your walls will have a lighter tone. But if you applied a lighter floor, then dark wall paint will go with it.

By following these three factors, you will determine the undertone easily; it will help you stop clash in walls colors:

  • Cool undertone: The wall paint is grey with Blue, which will result in a cool undertone. By this factor, you can determine undertone is cool.
  • Blue cast: Focusing on the direction such as north direction will reflect you as a blue cast wall.
  • Warm Furnished room: If your room is furnished with a warm tone, it will clash with cooler tones. So when you choose a more relaxed style for your walls, you must select furniture in a calmer tone. Otherwise, it will clash. 

Mixing of grey Colour with other shades:

There are different shades found when you mix different shades to come out with various blue shades:

Sky Blue: Mix 6:1, 6 portions of white and 1 portion of blue colour, You will get the sky blue colour.

Cornflower Blue: Now take the same sky blue mixture and put 2 portions of blue colour, and mix it. This proportion will be 7:2 as 7 for sky blue and 2 for blue colour.

Grey Blue: 

Now as you get sunflower blue. You have to take the same sunflower blue mixture. And put one portion of black and one portion of white in sunflower blue mixture. Mix it nicely; now you will get the dark blue shade. Its proportion is 9:1:1. As 9 is for Cornflower Blue, 1 ratio is for white, and 1 ratio is for black.

Grey with less Blue:

As the dark grey-blue mixture is ready, now if you want to make it light then mix 1 portion of Orange and 1 portion of white in the dark grey-blue mixture. You will get less blue shade. Now you have proportion 11:1:1, 11 ratio is for dark blue, 1 is for white, and 1 ratio is for Orange.

Warm vs cool grey:

There are many neutral colours, including grey, black, white and brown.

You can consider it as:

If you take black and white = grey, it will result in grey.

You can mix any colour in black while making a grey colour, but the white colour is completely white.

How to make a black:

To make a black colour mix blue+brown shade then it will come out as a black tone.

If you have two portions of Blue and 1 portion for brown, i.e. 2:1, it will result as cooler black colour.

If you mix 1 portion for Blue and 2 portions for brown, i.e. 1:2, then it will result as warmer black.
