This is being addressed as we speak in case someone were to use it at a high strength or spill a large amount even in pure form.
For many reasons if that were to happen, I would still suggest maybe rinsing at a later time....but we do also personally enjoying spraying a leaving in some situations without rinsing (but less concentrated)
It is pretty highly concentrated...and we are not going to change the concentrate of odor elimination, but change the color a little...and probably something most wouldn't notice....but might be more forgiving if a situation where to occur and it wasn't rinsed.
The color coding has been a bit intentional currently to help with identifying products that could have labels fall off in a van, or just even simple to see and grab by color.
Thanks for the follow up information.
