Ken,
Congrates on your new neps.
xLady pauline
Lady pauline is really easy to grow but if you wish to mist it with cold water,it will be fine but you have to do it everyday routine.What i mean is don't spray today and forget misting it tomorrow.They do't like temperatre drop after acclimatizing to lowland condition.Is better if you don't mist it with cold water.
Maxima x fusca
This is a hybrid between to easy nepenthes.Although it is highland,they will grow wonderfully for you in LL conditions.
Adult pitcher pic.It is called as xGentle velvet although people usually refer it to xGentle or xVelvet.
Viking
As what Fauzi told you,viking's pitcher will be more red if the pitcher is hidden somewhere in shady condition.The colour will bleach out too if exposed to direct sunlight.
Albomarginata
This species can take full sun and it need full sun for the pitcher to be red.
It's also a species which can thrive in lower humidity other than truncata.
The main thing to grow neps beautifully is how you're growing your neps now.
If your plants is pitchering big for you,means they like the conmdition you'ere giving them and all the neps should do well.
Keep us update about your plant.
My viking is growing healthy though and can't wait to see the pitcher.
