I'm afraid you can't. Blue and red make purple.
blue ..
it matters on how much of the 3 colors you had. if you add more blue and yellow you'll get a red tinged green color. if you add more red and blue you'll get a yellow tinged purple color and if you add more red and yellow you'll get a blue tinged orange color. if you add a pretty equal amount of each color you'll get a mix of either gray, brown, and/or black.
Yellow is a primary color, meaning no colors are put together to make it, it is just there. You can add just about any other color to yellow to make different types of yellow, though. If you add too much of a certain color, (not including yellow), to yellow, it morphs into a totally different color. An example is adding an equivalent amount red paint to a certain amount of yellow paint. You will get the color orange as a product.
You add so much yellow to the color blue that it doesn't look blue/green
well, you can add more white and orange color, then i hope that you'll get a brighter yellow!
You can add the color blue to make purple more blue.
You don't mix anything with brown to make purple because the color brown is darker than purple, and adding another color to brown would only result in a darker brown. Purple is made from red and blue.

blue and red. I even add some yellow to make it look cool-jk, but u can!
Any combination of the tree primary colours will result in some form of brown. As purple is red & blue and you want to add yellow you will get some variation of brown.
You can make a color duller by adding its opposite. If you look at a color wheel you will see what I mean. Here's what you add to make the following primary and secondary colors duller: red- green green- red purple- yellow yellow- purple orange- blue blue-orange
Red and blue make the color purple, but for dark purple you would mix red and blue together and add a bit more blue than red to make it darker.
Red, Blue, and Yellow combined in different ways make every color. Blue+ yellow= Green, Blue + red= purple, red+yellow=orange, those are the basic combinations. You can also add white or black the darken or lighten a color.

orange and purple combined make a reddish- brown. The reason is orange is red plus yellow, and purple is red plus blue, the three primary colors are red, yellow, and blue. When they are combined they make brown. You will add one additional red in using the orange, thus, the reddish hue in the brown color resulting.
