i want to dye my hair back to its natural color (light ash brown). it is currently orangey blonde. i am using a semi-permanent color. should i chose a color slightly darker than my natural color?? if i chose my exact color--wont it turn out too light?

If you use a semi- it will wash out real fast. unless you do go a little darker... if you use a permanent it may last a little longer. it is always tricky dying back to your natural. good luck!
