With the understanding of color theory, you can follow these steps to obtain your red color.
1. The first thing you should know is that red is not a color that can be obtained by mixing other colors. This is simply because red is a primary color, just like yellow and blue.
2. So, obtain the red color itself and add other colors to it to change its hue.
3. You can still add white or black to it in order to alter the value of the color.
Another method you can use to obtain a red color is by adding red paint.
1. First of all, prepare several colors of paint.
2. Examine and get the one(s) that is or are pure red.
3. Try to mix other primary colors that are blue and yellow with red.
4. Mix orange and violet with red paint.
5. You can also add a green color to the red in order to obtain something like a reddish-brown color.
6. Add a little white and a little red to fresh red paint so as to alter the tint.
