Maybe the tiles need to be rearranged in a way the yellow blocks become invisible!

Using Build with Chrome make a 7×7 cube.

Looking at it now it becomes clear that morse is the cipher.
Red blocks are – and blue blocks are .

Start reading from the top line facing north then continue on the top line facing east, south & west.
Then repeat but from the second line and so on.

Here are all the faces aligned north, east, south & west to make it clearer:

--... -.- .--. --.- ----. ... -.-. ..- .-.. .--. - -.-. -.... --. ..--- ....

The colours of the petals are the key to the solve

Get the RGB values for each of the petals reading the flowers like so:
  2  
1 3 5
  4  

	R	G	B
Flower 1	56	99	101
Flower 2	104	53	115
Flower 3	113	117	105
Flower 4	100	106	50
Flower 5	119	50	121

56 99 101 104 53 115 113 117 105 100 106 50 119 50 121

Look at the distribution of the red and blue tiles

This image has way to many colours just to throw you off.
A height of 3 and the fact the the width of 34 can be divided by two hints to braille.
Now we need to figure out which colours are dots and spacers.

Let’s split everything up in pairs

We know that numbers in braille only use the middle and bottom rows.
Looking at tiles 1, 5, 14 & 16 we can presume that only the red and blue tiles will represent dots.
Remove all other colours

Counting the dots on the first 2 tiles gives 6 and 9 which gives FI which is a good start for FIVE. Now why some are going down ?

For all brick going up count the dots for colours.
Bricks going down are a bit tricky.

Dots above the black line represent 10 & 20 and from the line down what you need to add.

You should get the following:
6 9 22 5 20 17 6 14 9 14 5 15 18 4 5 18 5 4 16 6 15 21 18 18 19 5 22 5 14 10

Width is 8 long which indicates the encode. The hint you need to replace the colours is in the filename.

First step, place all the tiles to make a perfect 8×18 rectangle.
Note: Some colours are not the same but do respect wether colour is “hot” or “cold”

With a width of 8 there is a good chance that the code uses binary. Just too many colours since binary is 0 & 1.

The filename is hot-and-cold.jpg, cold colours (blues, greens & purples/greys) are 0, hot colours (reds, oranges & yellows) are 1.

Start from the top and work you way down:
01100111 01100100 01111000 01101101 01110101 01110011 01100101 01100111 00110100 01110001 01110101 01100101 01110011 01110100 01101001 01101111 01101110 00111001

This code format is used for anomalies. It was the first code for the Obsidian anomaly of April 1 – 2, 2016

The index is the 26 pieces at the top of the image and represents the alphabet. Read left to right from the top to get A to Z.

From the bottom line just match the pieces to the index:

twofznninevictorseightvfourw

2FZN9VICTORS8V4W

Some are high, some are low and some are flat but the last blue piece looks like a sign and give it away

The index is the 26 pieces at the top of the image and represents the alphabet. Read left to right from the top to get A to Z.

Pieces that have a height of 3 are uppercase letters, height of 1 lowercase and the flat pieces are numbers. No dots is 0 and that last blue piece is what it is, an equal sign.

From the bottom line just match the pieces to the index:
