Fonts and colours are important for conveying the intended message and target audience of a music magazine. The right fonts and colours can attract readers and influence whether they buy the magazine. Serif fonts appear older while sans serif fonts like Franklin Gothic Demi look modern and stand out in magazines. Larger, bolder fonts catch readers' attention. Colours also send messages - red may convey passion while blue represents relaxation. The author discusses appropriate and inappropriate font and colour choices for different music genres like rock to effectively target the right readership.
