I thought I would share a free colour mixing hack I have discovered in the last couple of weeks. If you are having trouble matching a colour from a reference photo with the colour you mix on your pallet, and you want to try mixing a close match without wasting expensive paints or too much trial and error this may help. I started painting in November last year using acrylics after watching some of Sam’s painting tutorials on YouTube. I soon discovered how easy it is to mix colours that looked nothing like the colour I was trying to achieve. The subsequent trial and error process was a bit frustrating and wasting expensive pigment. Here is my solution: 1. I take a reference photo and copy it into powerpoint; 2. Create one or more rectangles beside the photo and use the eyedropper to fill each rectangle with a colour picked from the photo; 3. Open Microsoft Copilot; 4. Select one or more of the rectangles filled with the colour picked from the photo; 5. Copy and paste the rectangle into the Copilot “ask anything” box; 6. Type this instruction or something similar into the “ask anything” box alongside the coloured rectangle.. “how to mix the attached colour in acrylics using a mix of all or some colours ultramarine blue, titanium white, burnt sienna, yellow ochre, cadmium yellow light, quinacridone magenta, cobalt teal, alizarin crimson” 7. Push the enter button, and wait a few minutes; 8. The response you should get is a step by step colour mixing guide tailored to your specific colour swatch query as follows: Peter, this one is a light, clean, gently cool blue‑green — not turquoise, not sky blue, and not mint. It sits right between cobalt teal + white and a softened ultramarine mix, but without the strong green punch of teal or the violet bias of ultramarine. It’s a beautifully balanced, airy colour. Here’s the most reliable way to mix it from your palette. Understanding This Colour • Hue: blue with a slight green lean • Value: light–mid • Chroma: moderate (fresh but not intense)
