Lavender Buff Columbian x Lavender Partridge Brahma (Isabel) - what can I expect??

Hi all - wondering if someone has a thought as to what I can expect from this cross - I know they will be lavender something but is the columbian gene dominant to partridge or vice versa..or will it be a certain ratio of each color? Tried to use the calculator but it is too advanced for me lol

Here is one of the Brahma x - Feather & Fern Farmstead
