Mesh darker than asset

I am trying to make my 2D mesh render sprites with the same brightness as the original file.
.
On the below picture, the mesh on the left is darker than the UI Image on the right, which is an exact likeness of the original file. How can I make the mesh as bright as the Image? I believe that I essentially want to apply 100% equal lighting across the entire scene or remove lighting from the equation altogether.

I’ve tried to use Global Illumination but I’m missing something.
.

The only change that has made a positive impact was raising the Environment Lighting > Ambient Color to #FFFFFF, but it still is darker than the raw sprite. It also appears that Environment Lighting > Ambient Color > Intensity can affect the brightness negatively but any values >= 0 yield the above result.
.
All other lighting settings both globally and on the Mesh Renderer are default.


The import settings for the sprite are below:

The issue was in the Shader settings attached to the Mesh.
Changing from Shader Standard → Shader Unlit/Texture, solved the problem.
