Add visual interest
Texture in graphic design is used to imply a sense of feel which can be very effective at capturing the attention of the viewer. While texture can be used in a variety of ways — such as to creating a 3D effect and adding depth to an image, making use of texture in design can help your imagery feel more engaging and awe-inspiring.
Evoke emotion
Textures, even in the physical sense, can easily evoke an emotional reaction, though dependent on the person and the texture at hand. As a result, when a texture is implied through graphic design, it too has the power to evoke an emotion in the audience viewing the graphic. While some textures might make the viewer feel uncomfortable, others might produce a more comforting or soothing reaction.
Strengthen your identity
Naturally, any texture used within your graphic designs should align with your identity as a brand. When done right, the use of texture in your designs should produce the desired reaction and emotions from your audience to be associated with your brand, allowing you to not only make a lasting impression but the right impression.
