As per the rules of use of the indefinite article, the indefinite article is used in its original numerical sense of one i.e. to denote that there is a single unit of anything, the indefinite article can be used to replace the use of number 'one'. Here since there are two paintings one black and one gold, the indefinite article 'a' or 'an' should be used before each noun in place of number one to denote a single unit of each. 'A' is used for nouns that begins with consonant sound. Since it is a specific museum, definite article 'the' should be used before it.
