Peace be upon you. Regarding this matter, it depends on the customs, as colors cannot be strictly defined since they vary from one country to another. For instance, yellow and pink may not be considered adornment in India, while they might be seen as such in another country. Additionally, color alone is not the sole criterion for adornment; there may be two types of clothing that share the same color, but one may be considered adornment due to its specific design, while the other is not. May you be successful in all good.
