Small sauces from velouté can be made from the velouté, or from the 3 secondary sauces. 

4. Brown Similar to Veloute sauce Also known as Espagnole
The difference between the two sauces is that espagnole is made with tomato purée and mirepoux for deeper color and flavor.
This sauce can be further refined into an extremely flavourful sauce called demi- glace
Demi-glace is the starting point for most other sauces

fast foods, like bacon or can be used on chips and baked
Beans

5. Tomato
Resembles the tomato sauce you put on pizza, but with twice the flavour and twice the steps to make it.
Traditionally they used roux to thicken the tomato sauce, but most chefs just use the tomato themselves to thicken the sauce since the tomato its self is thick
You can make other sauces from the classic tomato sauce these sauces include
Spanish Sauce
Creole Sauce
Portuguese Sauce
Provençale Sauce
This sauce is generally used for all pastas.

6. Hollandaise Unlike the other mother sauces
All the sauce really is, is a thickening agent and liquid.
