To mix the color #7d9a6d , which is a muted green, with acrylic paints, you can follow these steps to achieve a similar shade:

Mixing Instructions:

1. Base Color: Start with a base of Olive Green as your primary color. This should closely resemble #7d9a6d .

2. White for Lightening: If you want to lighten the color to match the tone more closely, add a small amount of Titanium White to the Olive Green until you reach your desired lightness. Be cautious with the white, as it can quickly lighten the shade.

3. Yellow for Warmth: To add warmth and brightness, you can mix in a bit of Cadmium Yellow or Yellow Ochre. Start with a tiny amount (like a drop) and gradually add more until you achieve the desired brightness without losing the green quality.

4. Black for Depth: If the mixed color appears too bright or needs to be muted, you can add a small touch of Mars Black. Again, start with a very small amount, as black can easily overpower other colors.

5. Mix Thoroughly: Use a palette knife or a brush to mix the colors thoroughly, ensuring an even consistency.

6. Test and Adjust: After mixing, test the color on a scrap piece of paper or canvas. Adjust by adding more of any of the colors (green, white, yellow, or black) until you achieve the desired shade.

Example Ratios:

• Olive Green: 3 parts
• Titanium White: 1 part (adjust as needed)
• Cadmium Yellow: 1 part (adjust as needed)
• Mars Black: A tiny touch (adjust as needed)
