i'm just gonna jump into my reasoning: the numerals. aperial numerals determine a lot about the behavior of each character in their respective band (like how doss and garon have similar animations since their numberlings are like each other's but mirrored, not to mention the composite fusions). the numerals seem to be more important than the names. and kinard's numeral... is 5 and pent fused together. so, maybe 5*pent is what kinard will represent!
HOWEVER, this also means exard will still be what i believed before: three shades of purple. exard's numeral seems to represent six*exund, or six*six*six. like i said, the numeral seems to play a major factor in how an aperialblock looks/behaves. what i said here applies for sevard, otard, ninard, abard, and so on and so forth.
