The following puzzle is a special tribute for zetamath, whose channel on Youtube just reached 1000 subs a few weeks ago.
This one is also a special thank you to him for sharing a great amount of original and beautiful puzzles that I've always enjoyed greatly, for the theme of this puzzle I put some colorful variants together and made a harmonic puzzle that utilized each of the variant so it's like one big basket full of tasty and fresh fruits. Difficulty should lie anywhere between 3.5-4 so I hope you enjoy this one here! :)

(there're plenty of rules for this one so read carefully first before doing so)

Rules:

- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.

- Digits in the killer cage (box 1) sum to 26.

- Outside clue shows the sum of the digits in the cells along the indicated diagonal is 38.

- Digits along an arrow sum to the digit in the circle cell attached to that arrow.

- A black dot with number shows the remainder between two cells when the greater digit is divided by the smaller one; a white dot with number shows the difference relationship between two cells.
Example for the remainder: 5 and 2 will have 1 in the black dot connected between them since 5 divided 2 is 2 as the result and **1 as the remainder**.

- Each of the colored line serves its own distinct purpose:
+ Green line: adjacent cells must have difference of at least 5.
+ Yellow line: adjacent cells must have difference of at least 4.
+ Red line: acts as renban, i.e. digits form a set of consecutive digits in any order.
+ Blue line: each segment of blue line in the boxes passed through has a sum of digits as N, if the line passes through the same box multiple times then each individual segment counts separately. The sums of two consecutive segments in consecutive boxes must have difference of at most 1.
For example, if R6C3 is 8 then sum (R7C2+R8C2+R8C3) has to be either 7,8,9.
It's also possible that the sum (R7C2+R8C2+R8C3) and R9C3 contain different values.
