[Solved] Weird greyish effect

i’m trying to texture a cube. i’m testing textures actually. and sometimes i have a weird greyish effect which completely dresses up in a different way the texture. it happens in a more, or less accentued way regarding the texture used, in both marerial preview, and rendered views

Both times you are in edit mode. In this mode the object is more grey so you can better see and edit the vertices, edges and faces. When you render it it will look fine.

True. Thank you very much
