<em>The poster includes </em><em><u>bright</u></em><em>, pretty colors to catch the viewer’s attention and evoke a sense of joy. </em>
The most accurate and precise replacement for “bright” would be the word “vibrant” because “bright,” means to give off or reflect light, and the poster probably did neither. “Vibrant,” on the other hand, means colors that stand out/are striking because of hue or contrast.
The first one is the answer because pale has neither or negative or positive connotation and arrogant has a negative connotation. hope this helps! <span />
