Testing

Sprites Showcase

Stocking changed color depending on player's skin colors

Additional information

• I made the sprites with Alpha Channel because i believed that the charm of stocking is it's semi-transparent nature thus changed the color value depending on whats beneath it.
• I've set worn alpha value at 145 and for item at 200 because i believed it's the most optimum color to transparency ratio that will allow you to see enough of changes of color depending on player's skin colors and background also i think it's the most important thing of a stocking.
• And lastly i strongly urge that future artists that planned to remake or cleanup stocking sprites to implement Alpha Channel on their sprites when it is appropriate.
