M4A1-S Solitude Guide

On the 14th of August, the M4A1-S Solitude skin was introduced to the game as a 90 day limited edition Armory Pass skin, purchasable for 25 stars. In this Guide we will cover how the patterns are generated and the best ones you can get, and how you can take advantage of the situation to profit.
How does the skin work? When you are looking at a Solitude skin, there are 3 variables to consider:
1. Wear of the skin
2. Image pattern
3. Colour template

1. Skin Wear
Skin Wear Percentages are distributed as followed:
FN: 10%
MW: 11.43%
FT: 32.86%
WW: 10%
BS: 35.71%
The majority of the skin’s value will be in Factory New. If you are thinking about picking one as an investment, the wear percentages make a significant difference and you should mostly be looking at Factory New versions as they are the most sought out..
2. Image Pattern:
The M4A1-S Solitude is based off of this image of mountains, clouds and a sun:

The position of the mountains, clouds and sun will change for each pattern. The ideal position is to have the Sun in the middle of the gun for best visibility. You can also get patterns with 2 or 3 suns on them which could bring more value to the skin.
3. Colour Template
The colours of the skin changes based on this image:

The image above changes the colour of the mountains, sky, sun and clouds and determines its pattern. The top of the image has a small line which has inverted colours. Because of this small line at the top of the image, you can get patterns with a red sun and gold mountains (rarest patterns).
Types of patterns:
1. Gold Mountains
2. Green Mountains
3. Dark Blue Mountains
4. Light Blue Mountains

Best Gold Mountain patterns (Rarest Skin Pattern):
#1 Gold Mountain Pattern: 304 which has a fully visible red sun, it is the best M4A1-S Solitude pattern overall. Indeed, it is the only pattern which has golden mountains and where the sun is also fully visible.

Other Tier 1 Gold Mountains patterns: 95, 154, 220, 533.

If you are looking to invest into an M4A1-S Solitude, the safest bet is to get a low float version in Factory New with a visible sun. The rare golden mountain patterns are expected to be expensive and sought after. The chances of getting a Factory New Gold Mountain pattern is 1 in 625.
