$$ Create a new tibble called $$diamonds$2$ that filters out all diamonds that have a y value smaller than $3$ or greater than $20($retain diamonds between $3$ and $20).$

$$ Create a new tibble called $$diamonds$3$ that takes diamonds$2$ and adds a new column that contains the word $$colorless$$ if color is DEF or $$yellowish$$ if it is any other color code.

$$ Create a new tibble called $$diamonds$4$ that uses a filter to only include diamonds with carat weight greater than $2$ and color of $$colorless$.$
