Callan 正在探索如何使其广告素材设计更加独特，让受众在看到新广告时能认出他的品牌。要保持一致性，他可以考虑哪些建议？请选择所有合适选项。

To create a recognizable brand identity across ad creatives, Callan should focus on consistent visual elements. Using similar colors helps establish a distinct brand palette that audiences will associate with his brand. Incorporating the brand's logo prominently in each ad is crucial for immediate brand recognition. Similarly, using similar icons reinforces visual consistency and strengthens brand recall. Using the exact same image in every ad would lead to ad fatigue and limit creative messaging. While consistent messaging is important, using the exact same copy in every ad would also quickly bore the audience and prevent tailored communication for different campaigns or audiences.
