The color of red

[Patt Legg]

I am not sure whether this is the correct place to ask but here goes:

The color red. I have a real problem at times when I attempt to lighten or highlight a red object such as, let's say, an apple.

I have painted enough to know a red apple is not just red but multiples of various shades.

I have also heard that one should lighten with color--not white. Of course I know this.

I also know that there are a number of reds out there. I use Cadmium Red Light and Grumbacher Red as well as Alizarin. Using an apple for example, what do some of you use to lighten the red where direct light is hitting it and the finishing highlight

I know this is a "portrait forum" but red is used so often in so many instances, such as in a lady's dress.

Any exact ideas and varying in reds used would be most apprecitated.

Thanks
