It’s the different flection endings of the verb. The black part is the stem that usually remains unchanged (at least in the same tense), while the green part is the ending that changes depending on the pronoun it refers to.
In language, there is a model of referring to “stems” and “endings.” The stem of a word is the part that doesn’t change when it is being conjugated (or declined, depending on the langage). The ending (part in green) is the part that changes depending on whether the verb is 1st, 2nd, 3rd person, singular, or plural.
