/v2/skins: colors differ on different languages

https://api.guildwars2.com/v2/skins/263?lang=enhttps://api.guildwars2.com/v2/skins/263?lang=de

at least on one language, I get lots of "color_id": 1 (which is basically no color as 1 = dye remover)

Not sure what you're trying to show here; the only difference between those two responses is the item name. What colors are different?

?lang=de returns

        "AsuraFemale": [          {            "color_id": 442,            "material": "cloth"          },          {            "color_id": 480,            "material": "cloth"          },          {            "color_id": 19,            "material": "metal"          },          {            "color_id": 1,            "material": "cloth"          }        ]

and ?lang=en

        "AsuraFemale": [          {            "color_id": 1,            "material": "cloth"          },          {            "color_id": 1,            "material": "cloth"          },          {            "color_id": 1,            "material": "metal"          },          {            "color_id": 1,            "material": "cloth"          }        ],

for me too.
