How to Mix Sky Blue with Oil Paints - Surprisingly Easy Colour Mixing

Here's that link again for my studio resources and colour list: First Steps Guide

The sky can be a blend of many different colours, but how do you paint a simple but impactful blue sky?
As mentioned in my previous video, my students often come to me with colour mixing troubles and fears. So, I thought I'd put together a couple of videos showing how easy it is to colour match oil paints to photo references. Today we look at mixing sky colours. Sounds simple, and definitely can be, but you might be surprised by my colour choices.

Ultramarine blue
Sapphire
Turquoise
Magenta
Spectrum Yellow
Titanium White

Looking at a simple photo I've never seen before, I did a quick painting showing you my process of mixing, applying, and blending oil colours.
