<p class="MsoNormal">to preserve the (living) colouration of specimens usually requires specific preservatives (which usually are not allowed to be used on exhibition anyway); what is still recognisable in preserved specimens is mostly the pigmentation pattern.
Melanophores can be easily damaged by UV radiation, so the question is not so much how much lux would be appropriate (or not), but how high the UV radiation inside the gallery would be. Usually, light levels should be kept as low as possible, a rough estimate
is "150 lux or less". If you have lamps that emit UV light, UV filters should be considered. Also (even faint) sunlight exposure should be avoided as best as possible (but you surely considered this).<o:p></o:p></p>

<p class="MsoNormal">For our new exhibitions we have some fluid preserved (ethanol) specimens that will be on display for the public. For dry mounted specimens we have lighting guidelines but for fluid preserved specimens it is thought that there are no restrictions
because ethanol does fade the colors anyway. I think that light can decolorate a fluid specimen too so that we need some standards for them aswell. <o:p></o:p></p>
