This project demonstrates the difference in results between two methods of color blending using stamps. ☛ Click the buttons to switch between the methods. ☛ Click the ? for information. ☛ Use the slider to change the color effect value (the hue).
This is a companion project to "Stamp Any Color": https://scratch.mit.edu/projects/1242580488/ In that project, I use the 3-stamp method. It seemed to me that it should be doable with 2 stamps, but it just kept turning out inaccurate, so I made this test to figure out what was going on. And the result is clear - in order to produce accurate results, either (1) the brightness value needs to be 0% or 100%, or (2) the R, G and B values need to be 0% or 100%. Combining intermediate values of both RGB channels and brightness effect causes inaccurate results. Consequently, the 3.stamp method is preferable. The Pen isn't entirely accurate either, so using it for reference color isn't optimal. However, the inaccuracies are so small that it isn't an issue here, so I didn't jump through hoops to correct them. https://scratch.mit.edu/projects/872155564/
