How should I dye my hair? ☺☺

I'm asking my husband to dye my hair tonight and I have two colors on hand currently. I have a mahogany and a crimson red. I wanted ombré but I feel it's a bit complex for anyone who isn't a professional, so I'm thinking of other things to do with these colors. I have already done peekaboos before and I want something different. I work in an office and since I have my feedback session on Monday I don't want to go too shocking. Any ideas of what to do though??? Open to any ideas!! :)
