+XMB Monochrome Theme
+====================
+
+Guidelines
+----------
+
+### Palette
+
+ * The icons have only one color, #f2f2f2.
+ * No semi transparent parts except for anti-aliasing purpose.
+
+### Layout
+
+ * The shape should be easily recognizable.
+ * The shapes should be, when possible, aligned to a 64x64 grid, but exported as 256x256 PNGs, to downscale nicely.
+ * The shapes should be included in a circle of radius 31px (except when the shape is itself a circle, then we make it smaller), to insure consistent sizes.
+ * Some special icons have a superelliptic shape with a substracted symbol. They have an associated content icon figuring the same symbol. Symbols should match.
+
+### Style
+
+ * The border radius are either 1px, or 2px.
+ * Lines are 2px.
+ * The level of detail is reduced, we try to represent every button, but we can void representing stickers or color changes.
+
+### Export
+
+The PNGs are better exported by the old Inkscape v0.48.5-4. Later versions causes a premultiplied alpha issue with our mipmaping and blending code.
