It would be tedious to explain the specifics of the TRIANGLE ATTACK, so I will spare you the details.
It is enough to understand that it is important to maintain the order of the vanilla palette.
In the case of armor, if you arrange them like this, they will roughly follow the order of vanilla.
Compared to Pegasus, few people use armor triangles, so there is no need to overdo it, but it would be a shame to ignore the vanilla tileset.
This Pegasus data I made the other day might help you understand a little better.
We have tried to maintain the order of Pegasus so that existing color schemes such as Vanessa can be used as is.
There are special colors that are unique to this data, so they cannot be exactly the same, but it is important to maintain them as much as possible.
