Texture display in Vieport

[wing-bend]

Hi,

have problem viewing textures in Viewport. They look dark and it is complicated to work in way. I have Quick Shading lines mode, and Materials enabled. Is there any chance to make my textures more visible in Viewport? It is not important to me to have light effects, shadows, reflections etc... Here is some examples that I have for now, and another example is what I am looking for (but with textures!). If it matters, Redshift is used for final render.

Thank you.
