Light warm periwinkle is the Light Spring blue: a light, clear periwinkle with just enough red in it to sit in a warm palette. It is five points from Light Summer's periwinkle, the closest cross-season pair on this page, and it is the one color a Light Spring and a Light Summer can buy for each other.
Light warm periwinkle is an anchor color in Light Spring. The nearest color on the same side of the warm–cool line is Warm periwinkle #7C8FD6, a True Spring color, at a distance of 18: close enough to mistake for it on a hanger, far enough to tell apart on a person.
At RGB 165, 180, 232 the blue leads, and the red and green are close together with the green just ahead. The red sitting that close to the green is what gives it the faint violet warmth. The lift in all three is what keeps it light. Pull the red down and add grey and it becomes Light Summer's dusty cornflower; darken it and it becomes True Spring's warm periwinkle.
A Light Spring wears it as the cool-looking color in a warm palette: a shirt, a knit, a dress, a scarf. It is one of the few blues that flatters a Light Spring, because the warmth in it agrees with her skin. It works with cream, light camel, soft stone and warm beige, and it pairs well with light warm pink, apricot and clear salmon.
Retail calls it periwinkle, cornflower, hydrangea, bluebell and lavender blue. Most periwinkle in stores is a shade cooler and greyer than this, which is the Summer version and is close enough for a Light Spring to wear. The warm one is rarer. Spring is when the most of it is in stores.
The nearest color is Light Summer's periwinkle at five points, close enough that most people would call them the same. The Summers' shared periwinkle is eleven points off and greyer, and Light Summer's lavender is twelve and more violet. True Spring's warm periwinkle is eighteen points away and deeper. Because it sits so near the Summer side, this is the color to share with a Light Summer friend; on her it reads a shade warm but it holds.
The nearest named colors in other seasons, by perceptual distance (ΔE in CIELAB; under 10 is hard to tell apart on a screen, over 25 is a different color).

Yes. Light Summer's periwinkle is five points away, under the threshold most people can see. It is the closest overlap between the two seasons in this palette. A Light Summer pairs it with soft white and light cool grey; a Light Spring with cream and light camel.
No. Lavender has more red and reads violet first; periwinkle reads blue first. Light Summer's lavender is twelve points away. On a Light Spring, lavender can look grey; periwinkle looks clear.
For a Light Spring: cream, light camel, soft stone, warm beige, light warm pink, apricot and clear salmon. Periwinkle with apricot is the pairing to try first. Avoid black and charcoal, which make it look cold.
It is a blue, so it reads cool next to coral, but it is the warm version of periwinkle. The red sits close to the green, which gives it a faint violet warmth. The Summer periwinkles push the blue ahead and add grey.
