From the manufacturer:
StarBrite Fire Orange is exactly that, fire orange! It has a slight brown hue to it which makes for an awesome warm, muted tone.
It can be used as a highlight or a contrasting color to blues and greens and works well with any tattoo style you may do.
Looks great when doing tigers and lilies! This color blends really nice with all the flesh tone palette
