    Creates a new RGB profile. In the pattern you can simply use '*' for a sequence of characters or use '?' for a single character. For Example: new String[]{ "MER_*_2*", "MER_*_2*", ""}
    
    Parameters:
    
    name - The name of the profile
    
    rgbaExpressions - the expressions for the RGBA channels. Only RGB expressions are mandatory, the one for the alpha channel can be missing
    
    pattern - Pattern to check if this profile can be applied to a certain product. Three patterns need to be provided. 1. Will be matched against the product type 2. Will be matched against the product name 3. Will be matched against the description of the product
