Every scanner needs colour adjustment! You can do it visually, if you don't want to invest in colour calibration - but calibrating yields better, more consistent results.
I do not remember the Epson scan software, as I use Silverfast for slides and negs, but even VueScan will provide much better results and has an integrated calibration tool - you just need the test targets.
BUT nevertheless what you would do here is: Make a prescan. Adjust the colour within the scan software by means of curves mainly, which at the same time optimize brightness and contrast. Only the last tweaking should be done with any colour correction tool. Then save these corrections as presets for Velvia. The next time you scan Velvia you simply apply the preset and your basic corrections are in place. This should be possible with almost any scanning software and the Epson software wasn't that bad, if my memory serves me.
In the example image, it looks as whether you have a too low colour temperature selected for the slide. If you simply make a white balance adjustment with the eye dropper (use the white wall of the white rim on the tires), most of the blueish tint should be gone already.
