Some of the colours are vibrant but others are more muted, and it takes a heck of a lot of pressure to laydown strong colour on the page. These wax-based pencils have very hard leads, so it's difficult to get a lot of pigment out of them without almost ripping the page. If you're wanting pale pigment or have a heavy hand pressure, you should be fine with these pencils.
As you can see from my picture they are quite scratchy looking, but they are clearly labelled on the back for 'children's use' so are not marketed as artist's pencils. They are difficult to blend due to their hardness, so bear that in mind before buying.
