Using a combination of references from Air Canada's various CRJ705s and other real-world references, I've been able to recreate what a Jazz CRJ700 opb Jazz would look like if they operated one. This paint uses 4k textures and uses 3D substance painting for the highest quality. 

Each aircraft's information is as follows:

Jazz Red: C-GJAZ, MSN 15036. Tail 701
Jazz Orange: C-FCJZ, MSN15040. Tail 703
Jazz Yellow: C-FDJZ, MSN 15041, Tail 704
Jazz Green: C-GDJZ, MSN15049. Tail 711

Livery features:

Accurate HD Leaf.
Accurate title sizing, fonts, and positions based on interpolation.
Official Air Canada colours.
Use of decals where applicable.
Use of 3D painting where applicable
4K textures.
Fleet number decals placed accordingly.

Tidbits of information

Jazz orange looks very similar to Jazz red, due to lack of resources, I've not been able to find a 100% accurate colour scheme. But based on various pictures, this is how the orange hue actually looks like. Similarly, all other colours were interpolated and researched, they may not be 100% accurate but they are about 95% accurate due to the age of this livery. If anyone has real, original, and official resources, let me know!
