I play as a Fire Elementalist so I want my character's armour to represent that in the form of a fire colour such as the one below. The only thing is I don't know how to make that colour. I assumed it was Orange/Red but that just makes a light orange colour.

How Would I Make This Dye Colour?

Try red with a darker color, like brown. Or orange/brown. or even red/green. combos like that sometimes produce nice dark colors.

Looks like just red to me...ehe

looks like it might be the original color the pyromancer armor came in. i haven't figured out which dye combo remakes that since they're all still a bit off. if its 15k pryomancer, closest you'll get to the old color is orange.

What I would suggest is try more than 2 dyes. What about 2 reds and a orange or 2 orange and a red, or something like that. I have a dye "recipe" for a gold colour where you use 4 dyes. So play around a little, maybe you'll get it just right.

meh you never needed more than 3 dyes for a mix - i miss my days of dye mixing ='[

Maybe... red, red, orange, yellow/brown?

While the new dye preview is great, the new dye results are terrible. It's almost impossible to get a bright or true color on most armor. A lot of them have a grayish cast to the final color.
