How are the words spray and streak alike

The words 'spray' and 'streak' are alike in many ways like they both begin with letter "S" and the both the words could be used in the context of color or paint as both the word expresses to end up in covering an area with color as spray stands for 'to scatter liquid in minute droplets' while streak stands for 'mark or band of color'.

However, the meanings of the word are not exactly synonymous to each other and have different pronunciations yet they are similar in some aspects like the initial letter and the context of covering up a surface with liquid(paint or color especially).
