Hi Storm, you've come to the right place!
So basically you want to, make Kid being Innate Blue, and that her 3 Element (Pilfer/Redpin/Hotshot) also Blue?
1) Kid Innate color can be easily edited by going to offset 13B72279
you should find the value "20"
The game use this table for innate color
Blue = 80
Red = 20
Yellow = 40
Green = 04
Black = 10
White = 08
So changing 20 for 80 will make Kid Innate color Blue (Only when she joins you, the game set the innate color before the character joins you, so changing it and loading in a game where kid is already in your party won't work! Make sure you test it that way
)
2) Her 3 elements can be found at offset
0026B43C - 0026B467 = @Pilfer
0026B468 - 0026B493 = @RedPin
0026B494 - 0026B4BF = @HotShot
and
13BA205C - 13BA2087 = @Pilfer
13BA2088 - 13BA20B3 = @RedPin
13BA20B4 - 13BA20DF = @HotShot
(The first set of value found are used in the Menu, lets says I only edit the Pilfer at 0026B43C , Pilfer info will only change in the menu , not in battle!
The second set is for the Battle! So You wanna make sure you edit both set to get your element properly edit ! )
Remember all element length are "2C". You can find lots of info at
https://www.chronocompendium.com/Term/2541.html also concerning element !
Element color use the same table as Innate color (and FC is used for ChronoCross element Color, Funny thing I haven't tried to put a Character with innate color FC , wonder what would that do lol!)
How to make Pilfer Blue :
So changing offset 0026B441 & 13BA2061 (Both value are 20 "Red" , change it for 80 "Blue"
and Pilfer will now appear as Blue element in Menu and in Battle!
How to make Redpin Blue :
Change 0026B46D & 13BA208D same as Pilfer!
How to make HotShot Blue :
Change 0026B499 & 13BA20B9
There you go ! Let me know if you have any other question!
*Small thing is : Sadly It won't change the color of the Redpin in the animation *When kid toss tons of pins*, I haven't found yet how to edit those).
