NGC 3576 variations

Very little data (under 2 hours) so figure something to experiment on. The rather colourful and starless versions are what they are but I was trying to work out what a faithful representation of narrowband data might be, with the intention that Ha is red (online sources suggest bright red?), SII being a darker red and OIII as a cyan of sorts. When the cyan mixes with the red this seems to result in a yellowish brown... really no idea with this....the red seems quite orange too?
