The flash tubes in the old Bowens Illumitran have a spike at 470nm but the chart is then relatively flat all the way to 680nm.
High quality Neutral Density filters flatten things out nicely — apart from the burst of heat starting at 680nm :)
We’ve never had any problems with colour reproduction using Nikon sensors like the D800E & Illumitran.
The reproduction issues are all about keeping the originals clean and flat :(
