A spark is a spark is a spark, and it either ignites the fuel or it doesn't. Once the fuel is ignited, the spark does not matter any more, it has done its job.
I'm sure you have heard the term "pushing the envelope". With ignition, there is an envelope. With an optimum air/fuel ratio, there is a wide range of spark that will ignite the mixture. I don't think there is too much spark, but there certainly is too little. The too little forms the bottom of the envelope.
With an optimum spark, there is a range of fuel air mixtures that it can ignite. This forms the edges of the envelope and are called LEL (lower explosive limit) and UEL (upper explosive limit). As the spark becomes less optimum, the side of the envelope will come closer together. As the fuel/air mixture approaches the edge of the envelope, the bottom of the envelope has to be higher.
Anytime the spark and the air/fuel are inside the envelope, there is ignition, regardless of the color of the spark.
