    # Create lattice matrix A
    np.random.seed(int.from_bytes(matrix_seed[:4], 'big'))

    # Generate secret and error vectors
    s = np.random.randint(-B, B+1, size=n, dtype=np.int32)
    e = np.random.randint(-B, B+1, size=n, dtype=np.int32)

    round1 = hmac.new(hmac_key, base_data + geometric_seed, hashlib.sha256).digest()
    round2 = hmac.new(transform_key, round1, hashlib.sha256).digest()

    # Generate RGB

    r = (combined * 17 + 113) % 256
    g = (combined * 23 + 181) % 256
    b = (combined * 31 + 229) % 256
