Re-coloring of the receipt in the receipt-book

let’s say i found new book. book contain new receipts. in the receipt-book need somehow color new entries - and all the entries need to be coloured

dark-grey - in the our memory but not may be build
bright-white - in our memory and can be build
AND i propose new colors
yellow - entry from the book and can’t be build for some reasons.
green - entry from the book and yes we can build this. and we need to build for "memorising scribes"©eye of the beholder

after some success builds of green entries - green turns to bright-white
ok not green - but green type of colour.
