Orange - looks great and stylish.
Concept - Inventory, weapon stats, armor, skills, upgrade cards. We decided to completely redesign the interface for our game for the fourth time in five years. steamhappy First, draw the concepts and edit them in Photoshop, and then cut and lay them out in Unity.
Concept - Weapon change screen. Colors indicate rarity. Physical and shield damage.
Concept - Forge. Upgrading cards and skills. 3 cards turn into 1 of the next level. The concepting process took several months. It brought many changes to the way the player interacts with the game (UX).
Concept - Global map. Story and side missions. Difficulty - the more difficult, the greater the reward.
Concept - Pause screen. Minimap, mission objectives, found loot. Orange is really cool. Bright, attractive, contrasting. But in the game you need to interact with the inventory a lot:

• insert fire damage card into the sword
• paint body armor to dark green
• upgrade ricochet card in the blacksmith
• disassemble the helmet for spare parts to use it in your Sniper rifle
• sell looted trash
• read about exotic perks in new dropped energetic shotgun
• assemble your own set of armor
• etc

In the end, we changed orange. Because player's eyes started to physically hurt after half an hour of playing. The new color is not as stylish, but it is classic and practical.
