Today's Challenge will test your skills of visualization and sequential reasoning:


From infrared to ultraviolet, it’s difficult to write without light. To reach the goal, convert the seen into the unseen.

Hint 1

The order of the colors does not matter. You can sort the colors in the order indicated, from infrared to ultraviolet, but that's an optional step.


Hint 2

The + and - numbers suggest a certain kind of cipher.


Solution

There are a number of steps and a couple of paths to getting to the solution.

Path #1:

1. Start with the colors given in the image (R = red, O = orange, Y = yellow, G = green, B = blue, V = violet; there's no indigo):

OYGB ROB RB YOBG BRO YRB
BORY GYRB RO OG BOYR GRB
OYG GR BOR R GOYR BYGO BR
ROBY RYB YGRB RB OBVG
RBY YORB BGR GOY BYOG
BOR GO ROYB OGBY VYGBR
ROG OG OVYR BR BGYO RBO
YORB RBY VYR GROB ROB
GOR YBR RBYO BYGO RVGBY

2. Sort the colors in each group from infrared to ultraviolet (optional):

OYGB ROB RB OYGB ROB RYB
ROYB RYGB RO OG ROYB RGB
OYG RG ROB R ROYG OYGB RB
ROYB RYB RYGB RB OGBV
RYB ROYB RGB OYG OYGB
ROB OG ROYB OYGB RYGBV
ROG OG ROYV RB OYGB ROB
ROYB RYB RYV ROGB ROB
ROG RYB ROYB OYGB RYGBV
This step simply makes the following one a bit easier.

3. Convert each group of colors to a unique letter.  For example, replace all the combinations of OYGB (in any order) with "A", all the ROB's with "B", etc.

ABCABDEFGHEIJKBLMACEDFCNDEIJABHEAOPHQCABEDRSBPDEAO

This is a substitution cipher that can be solved by replacing the letters (A=T, B=H, C=E to get the first word "THE", etc.) or using a Cipher Solver such as QuipQiup (← click this link). This results in:

THE THORN BIRDS CHAPTER ONE WORDS THIRTY FIVE THROUGH FORTY

4.  Looking up the named book, The Thornbirds, and reading the 35th through 40th words, gives us:

SQUATTED DOWN BEHIND THE GORSE BUSH

The +/- numbers in the image look like ROT numbers. They can be converted to a key for a Vigenère Cipher, where each letter of the text is converted with a different ROT number (0 = A, -1 = B, +1 = Z, etc.). Using the key AOMWGAWYVMJNPAPPCSTAERZTSRTISW to decode the six words from the previous step results in:
SCIENTIF ICNA MESTLL AHA PPYAN IMAL

6. The second part of that is a short URL link, namely stl.la/happyanimal . This redirects to a YouTube video Quokka The Happiest Animal in the World . From the first part, we need the scientific name of the Quokka, which is Setonix Brachyurus. The solution is stl.la/setonixbrachyurus .
