ROSE Online uses 20x20 pixel clan marks saved as 16-bit A1R5G5B5 BMP files. The A1 means 1-bit alpha channel - pixels are either fully visible (alpha=1) or fully transparent (alpha=0). Colors use 5 bits each for red, green, and blue.

Save the downloaded mark.bmp to your ROSE Online folder (typically C:\Program Files\ROSE Online). In-game, press Alt+N to open the Clan Window, click the 'Edit' button next to the clan icon. Browse to select your mark.bmp, preview it, then click 'Confirm'. Only Clan Master or Deputy Master can change the clan mark.

Yes, this tool is compatible with the ROSE Online re-released by Rednim Games. The format specification (20x20, 16-bit A1R5G5B5) is standard across most ROSE versions.

The 16-bit A1R5G5B5 format only supports 1-bit alpha transparency - each pixel is either fully opaque or fully transparent, with no gradients. Anti-aliased or soft edges become jagged. For best results, use bold, simple designs with clean edges. Avoid soft shadows or gradient transparency.

Use the 'Preview Backgrounds' section to see your mark against different colors. The rose/pink background simulates how it appears on the clan window. The 1:1 preview shows actual pixel size. Remember that in-game rendering may vary slightly.

Simple logos, pixel art, bold icons, and text work best at 20x20 pixels. Avoid photographs, gradients, or detailed artwork - they won't scale well. Use the AI Enhance tool to clean up resized images. PNG with transparency is recommended for source images.

Upload a PNG with transparency or use the pixel editor's eraser tool. Transparent pixels will show the clan window background in-game. The checkerboard preview shows which areas are transparent.

The 16-bit A1R5G5B5 format has only 32 levels per color channel (5 bits), compared to 256 in standard images. Colors get quantized to the nearest available shade. Use the preview to see how colors will appear. Bold, primary colors work best.

Gradients don't work well due to the limited color depth and 1-bit alpha. Semi-transparent areas become either fully visible or fully invisible. Stick to flat colors with hard edges for best results in the A1R5G5B5 format.

Your clan mark appears in the clan window, above clan members' heads in-game, on the clan rankings, and during clan wars. The small size makes bold, simple designs most recognizable at various display scales.
