What crazy colour dyes do I need?

I am after a burgundy hair colour, like darkish red with a hint of purple. I have applied feria scarlet power to my light brown hair I like this colour but I know it will fade quickly so I thought if I buy a veggie dye this will help combat that? However I hate the staining these cause so I mixed some in my conditioner, as it is only to stop fading and top up colour. I mixed a rough ratio of 1 (colour) 4 (conditioner) using directions plum and crazy colour bordeaux. I shampooed my hair then applied the mixture to damp hair and left it for 30mins before rinsing. What I want to know is what colour would u recommend me to use? And also have I done this correctly?? Shall I leave it on longer? Shall I mix less conditioner etc? Also the result of the colour is nice but not quite how I want it. I will try and attach a photo of my goal colour, and the mixture I applied 🙂
