is there a tool to determine item hues due to the possibility of screen image being different against background or like me I dual screen single box and the colors verry very slightly.
Newest razor version has the -hue command. Or, in any razor version: Or the ingame options via house inspector tool or house decorator. Both work.
Usually the anniversary clothes, especially with the anniversary naming on them. Apart from that some high end BOD clothes, mainly 1150 have value. And 1109 is valuable too, it only drops in evil mage towers, not from evil mage NPCs. That's about it. The rest can be farmed. Edit: Some other rare event clothes that are named, are valuable too. But it's more because of the naming than the hue.
