No you cannot, orange dye is already a mix of red and yellow.
use a red dye on a yellow dye to get orange dye
You mix red and yellow dye. If that is your question you can buy an orange at the Grand Exchange
I think you are mistaking the orange color for brown. The orange do really look like brown on normal capes. Anyways, mix red dye with yellow dye for orange dye. When you use the orange dye on a normal cape, you will get your " brown" cape.
Mix red and yellow dyes together. (use them on each-other).
You use one dye on the other.
To make orange dye, get 3 onions, and 5 coins for yellow dye. then get 3 redberries, and another five coins for red dye. go to the witch in draynor village and make the dyes, then mix the yellow and red dyes
you can make yellow blue red dyes in runescape. to make the dyes you need to go to aggie the witch who lives in draynor village. she will ask for some items and a little money. it won't exceed 5gps. for red dye.. you will need redberries and for blue dye you will need woad leaves..for yellow dye you will need onions
You need red dye and yellow dye, then just mix them together.
i would mix pink and orange hair dye (like mani panic) with conditioner (lots of it!)
You take food dye put it in pancake mix put peanuts in the pancake mix and make a ball with it!
probably chi red or the mix of chi red and orange.
I believe if you mix cinnamon and dark orange you get a medium reddish brown tint to hair.
