Colors that are directly across from each other on the color wheel complement each other. In this case, gold/yellow is directly across from purple on the color wheel. The exact color will depend on how much of each color you use, but either way you will end up with a brown color. You may even see a tiny bit of gray depending on the color of the gold.
The more purple you use, the darker the brown will be, but if you use more gold, it'll be a lighter color.
Using the same amount of paint/material in proportion to the other will create a muddy brown color. It truly depends on the specific color of purple and gold you use, and the undertones in each.
If the question is about paint, and "gold" refers to yellow, the combination with purple will equal a shade of brown, as is the case with all complimentary colors (colors across from each other on the color wheel, like orange and blue or red and green). If one were to add white paint to the mix, the result would be a chromatic gray, or a slightly tinted gray varied by color temperatures and mixing proportions. The process of mixing colored materials, like paint or ink, is known as subtractive mixing, referring to the light absorbed (subtracted) vs the reflected light that gives objects color.
I would agree with above. All colours which compliment each other and are therefore opposite will always make a brown. Red and green for example as well as orange and blue. Colour seems to follow a certain pattern and I am sure after looking at the colour wheel and different patterns between the colours you will start to notice this as well.
When we mixed color gold with color purple, we will get brown color. The ratio of colors for mixing shows darkness of brown color. If you mixed small quantity of gold color with purple, you will get light brown color and if you mixed high quantity of gold color with purple you will get dark brown color. Always mixed the colors in proper ratio as you required.
Mixing the color purple and the color gold creates a shade of brown. This shade of brown depends on the intensity and amount of purple and gold used.
