For a project that I am planning to work on in my free time, I concepted some designs for different screens, such as equipment (armour, weapons, etc.), etc.
The main focus of this design is to keep it simple and minimal. The white colour screams simplicity to me and also fits into the Norse ice-concept. The inspiration for the rectangular design, especially with the rotated squares, comes from games, such as God of War and ASHEN.
The main colour splashes within the design come from different levels of rarity for the equipment items (white = common, green = uncommon, blue = rare, purple = epic, orange = legendary), the red and green for stat increases and decreases, and the red which appears in the book for boss-enemies.
Of course, there will be more colours coming into the design down the line, but these are the most prominent ones for now.
