There are many species available. I have a special affection for dwarf irises (Iris reticulata), perhaps because they were one of my early successes. My first-ever bulb-forcing attempt ended mostly in disaster when a Christmas vacation took me away, and a severe cold snap froze my poorly sited bulb pots. Most of them were ruined, but these plucky, blue gems ('Harmony' was the cultivar) came through with flying colors. Another advantage to dwarf irises is their short stature. Only about 6 inches tall, they're great for table centerpieces at dinner parties or other places where taller plants might block the view. They come in a variety of colors. 'Natascha' is ivory with blue shading. For yellow flowers, try another dwarf iris, Iris danfordiae. It will bloom with very little chilling. Dwarf irises can do with as little as six weeks chilling time, but you can hold them in the cold for up to 10 weeks.
