Re: how to mix a bright blue sky colour

Maureen, lovely painting and yes, its a great example for me
Dayle Ann, good point about using the medium instead of water as I do have trouble with paint bonding to the surface if its too watered down. I've got Gloss and Matte Gel Medium, which one would be better. Or would Flow Enhancer be good ?
Elaine, thanks for the confidence and the colour ideas You know me, I always agonize
Robert, thank you too


Okay, went shopping and managed to pick up some Phthalo Blue W&N makes a Red shade and a Green Shade but they only had the Red shade in the shop. Will that be okay or do I need to watch anything in particular ?

Re: how to mix a bright blue sky colour

This is a very good approach to painting graded skies with acrylics,

The sky in the motorcycle pic? That's wet-in-wet watercolour on Yupo paper - probably 3 or 4 different blues in that, and then it was tweaked in Photoshop after I scanned it.

The piece with the gold circles in the blue background, though, has a ton of phthalo blue (red shade) in it. Many, many washes and glazes.

The one with the motorcycle is the one I meant alright That sky looks stunning
Phthalo Blue is an amazing colour, it can be so bright and transparent and yet so dark and powerful. I am glad I bought it

Nilesh, that was a great video link Thanks very much

Re: how to mix a bright blue sky colour

The technique the video illustrates is pretty much what I do-- it's a standard approach. The glazing medium has is a fluid acrylic paint base minus pigment with about 15% retarder added. I use it for glazing sometimes, and sometimes use GAC100 with a little retarder added, which amounts to the same thing. You can use the same material and technique to build up wonderful glaze layers on any part of a painting-- lovely for fabric, for instance. Each layer will deepen the color, or if over another color, change it in ways that are different from straight mixing. Glazing is very useful and fun technique in painting.

Re: how to mix a bright blue sky colour

as others have said it is not the colour but how you use it and what is around it that improves tones and colour saturation

a simple sky is achieved by a gradual blend of mid ultramarine and tit white at the top of the painting down to the horizon at the bottom wich should have been blended down to the lightest blue possible

blending white and ultramarine in a nice gentle believable tone is the first essential step other colours will only cause confusion and are superfluous to painting a blue sky as other blues have green etc backnotes more suited to water of sea scenes etc

then what goes on top makes the whole difference clouds can be done in tit white or flake white with a very slight hint of red or yellow ochre in top areas and shaddows in the clouds done in paynes grey and white mix

the colours used are very simplistic

the diffrence is learning how to tone your colours and learning how to observe

it is surprising how dark and how light colours are against each other when observed

try not o observe colour in large areas observe it in areas about the size of a couple of matcheads to see the true colour in that area

and also observe the difrence of how dark the blue actualy is against how white the clouds are the blue of the sky and grey in the shaddow can be quite a lot difrent to the white of the cloud

this is what will give you the vibrancy

here's a link to an artist i follow who has it to perfection this is a w.i.p. take time to look at his other works as he does variations http://www.artistic.flyer.co.uk/studio.htm

Re: how to mix a bright blue sky colour

I typically use Cerulean Blue with some Titanium White - keep it light and airy, and it usually works well as a sky, at least for me.

Ray, that's probably the best idea you've ever had.

Re: how to mix a bright blue sky colour

Thanks again Dayle Ann and Nilesh
Shadwell, thank you too You are very right about observing properly Trouble is, I have to make my sky up, no ref to go by.
Matthew, thank you too I couldnt make my Cerulean work

I ended up using Phthalo blue and white as a mix and lightly glazed some Ultramarine over the top part and some Tit. White/ Naples Yellow mix over the bottom bit. Its not perfect, but I am happy enough with it to leave it be for now.
